How much does interior design cost in Bangkok? Fees and budget factors

Interior design cost in Bangkok has three main parts: the design fee, construction and the furniture and fittings. A useful budget separates those parts and states what each includes. Below, a worked example in Thai baht shows how a percentage-based design fee is calculated, followed by the decisions that change the total: scope, delivery route, materials, site conditions and contingency.

First, separate the three costs that get mixed together

“Interior design cost” usually collapses three different things into one phrase. There is the design fee — what the studio charges to plan, design, detail and document the project. There is the construction cost — what the contractor charges to build it: demolition, walls, ceilings, floors, joinery, electrical, plumbing, painting. And there is the fit-out cost — loose furniture, lighting fittings, curtains, rugs, art and accessories, usually called FF&E. On most residential projects the design fee is the smallest of the three by a wide margin; the construction and FF&E costs are where the budget is decided. When a studio quotes a design fee and an owner hears a total, the conversation goes wrong before it starts.

Professional design fees: the TIDA reference (2008)

The Thailand Interior Designers’ Association (TIDA) identifies its professional standard as B.E. 2551 (2008). For residential interiors, classified as Type 2 (houses and apartments), the TIDA fee schedule reproduced by Baanlaesuan lists a basic professional design fee of 15% for an interior project budget up to ฿5 million. This article uses that dated standard as a reference. Gratitude Design’s project-specific proposal confirms the actual fee, calculation basis and services included.

To see how a percentage fee works, assume a hypothetical agreed fee basis of ฿3,000,000 for the interior works. At an illustrative 15%, the design fee would be ฿450,000. If that fee is charged separately, those two lines total ฿3,450,000 before any additional exclusions. This is arithmetic for planning, not the cost of a completed studio project or a price per square metre.

Before using any such calculation, confirm what the percentage applies to and whether the design fee is already included in the stated budget. Ask for separate lines for construction, built-in joinery, loose furniture and lighting, appliances, design and site services, VAT, building fees and contingency. A proposal should state which are included, excluded or provisional, along with the drawing deliverables, revision allowance and site-visit scope. For a project-specific budget, send us your floor plan, area, location and intended scope.

Scope is the first driver

What is being touched decides more than any finish. A full interior architecture commission — new plan, new ceilings, new electrical and lighting layout, bespoke joinery throughout, complete FF&E — is a different order of work from a fit-out that keeps the developer’s floors and bathrooms and adds joinery, lighting and furniture. Both are legitimate. The studio’s residential work covers both ends: The Bangkok Sathorn apartment was re-planned so that living, dining and kitchen became one room, with new joinery and a full material scheme, while the Setthasiri Donmuang house began as a finished developer shell and was transformed by layering — panelling over the walls, a new foyer floor, ceilings dropped where light had to be hidden, joinery built to each room. The first scope costs more than the second, and it should; the question for an owner is which one the brief actually needs.

Setthasiri Donmuang — a finished developer shell transformed by layering rather than demolition: a different scope, and a different cost, from a full re-plan.

Design-only or turn-key changes how the money is organised

The second driver is the delivery route. In a design-only commission, the studio produces a complete documentation set — interior architecture, joinery shop drawings, lighting and electrical layouts, FF&E schedule — and the owner’s contractor prices and builds it. The fee is for the drawings; the construction is a separate contract and the owner carries the co-ordination between the two. In a turn-key commission the studio that draws the project also builds it, under one contract, to an agreed price and date. The total is not necessarily higher — the contractor’s margin exists either way — but it is fixed earlier and carried by one party, which is why most of the studio’s residential projects, including Quarter31 and the Four Seasons residence, were delivered turn-key. The route to choose depends on whether you have a contractor you trust, how much time you can give the project yourself, and how much you value a single point of accountability. We have written separately on that choice in interior designer or turn-key contractor: who does what.

Materials: imported, custom, or considered

The third driver is the material list, and here the popular assumptions are only half right. Imported stone, European kitchen systems and branded furniture do raise the total, and so does a long finish list — every additional material is another supplier, another lead time, another trade on site. But the most expensive rooms the studio sees are rarely the most restrained. Quiet luxury, as we practise it, is a short material list handled with care: four or five finishes, one gesture per room, joinery drawn to the room rather than bought to fit. That discipline is not only aesthetic; it is what keeps a budget legible. The single largest variable inside “materials” is usually bespoke joinery — a wardrobe wall, a kitchen, a library — because it is made once, for one room, by hand.

The site decides more than the plan

A condominium and a house of the same area do not cost the same to build. In a managed tower the work happens inside permitted hours, materials go up a booked service lift with floor protection along the route, waste leaves the same way, and every deviation goes back through the management office. A branded residence adds a formal approval process on top. A house allows continuous work, easier access and on-site decisions, but exposes structure, roof and landscape that an apartment never touches. Ceiling height, the position of risers and drains, the age of the building’s services and whether the existing floor can stay all move the number before a finish is chosen. This is why the studio’s first drawing on any apartment is a plan of the fixed points, not a mood board — and why a price given before a site visit is not worth the paper.

The Bangkok Sathorn — a full re-plan inside a managed tower: fixed drains, a fixed ceiling zone and permitted working hours all priced before a finish was chosen.

Contingency is part of the cost, not an admission of failure

Every construction project carries unknowns: what is behind a wall, how level a slab is, what a building’s engineer will require once the application is in. A proposal that shows no contingency has not removed that risk, it has hidden it. A sensible budget holds a reserve against the unknown and the owner decides, at each stage, whether to spend it. On a well-documented project most of it comes back.

Why “price per square metre” misleads

Owners ask for a rate per square metre because it feels comparable. It is not. A rate averages the cheapest square metre in the unit — a corridor with a painted ceiling — against the most expensive — a bathroom in stone, a kitchen in bespoke joinery — and the mix is different in every home. A 120-square-metre apartment with two stone bathrooms and a full kitchen can cost more than a 250-square-metre one with one. The rate also says nothing about scope or route: design-only and turn-key, full re-plan and fit-out, all produce wildly different rates for the same area. Use a per-metre figure, if at all, to sanity-check a proposal after you have understood its scope — never to choose between studios.

What to bring to a first conversation

A floor plan if you have one; the building’s fit-out rules if it is a condominium; a frank account of who lives in the home and how; the two or three things you cannot live without; and, if you know it, a budget range. The range is not a trap. It lets the studio tell you early which scope and route the number can support, and what would have to change if it cannot. A first meeting with the studio costs nothing and commits no one — and it is where the honest number begins.

Quiet luxury interior design: 7 principles explained through Bangkok homes

The phrase has been worn smooth. “Quiet luxury” now describes a palette — oatmeal, bouclé, limestone — and a mood of expensive understatement, and it is applied to almost anything that is not gold. That is not what we mean by it, and it is not what our clients are paying for. When the studio describes its residential work as tailored luxury, quiet rather than loud, it is describing a way of making decisions, not a colour card. Below are the seven decisions, in the order they are made, with the houses and apartments where they were tested.

Proportion before anything

The first luxury in a room is that its parts are the right size for each other. It is also the one a visitor never consciously registers — they feel that a room is calm without being able to say why. At Quarter31, a 410-square-metre house off Sukhumvit 31, the double-height living room was given exactly three things to do with its height: a full-height ink-wash mural over the dining table, a two-storey wall of storm-figured marble behind the television, and a fall of seeded-glass pendants between them. Everything else in the house is held to furniture scale. That is why four hundred and ten square metres reads as calm rather than grand — the volume is spent in three places and nowhere else. Proportion is decided at the section, before a single finish is chosen, and it cannot be bought back later.

Quarter31 — a double-height room given three things to do with its height, and nothing else above furniture scale.

Material that improves with use

Loud luxury is a finish that photographs well on handover day. Quiet luxury is a material that looks better after five years of hands and weather. The difference is not price; it is how the material behaves. Stone with real figure, timber that takes a patina, leather that softens, lime plaster that holds light — these get better. High-gloss lacquer, printed veneer and mirror-polished metal get worse, and they announce themselves in the meantime. Across the studio’s apartments the palette is held to four or five materials each — smoked oak, bronze and pale limestone with a single dark book-matched stone at The Bangkok Sathorn; oak, tan leather, white panelling and travertine at the Ritz-Carlton Residences — and each room is allowed one gesture. The restraint is not austerity. It is what lets the one gesture be heard.

Light, mostly hidden

In every residence the studio has completed, most of the light comes from somewhere you cannot see: coves that wash the ceiling, shelf edges lit from within, cabinets that glow behind glass, a ribbon of warm light along a counter. Downlight grids belong to offices. Hidden light does two things a visible fitting cannot — it makes a ceiling feel taller than it is, and it lets the room change with the hour, so the same living room reads differently at four in the afternoon and at ten at night. At The Bangkok Sathorn the lighting is almost entirely indirect so that the city outside stays the brightest thing in the room. That is a deliberate hierarchy: the view first, the room second, the fittings not at all.

Craft you can touch

Quiet luxury lives at arm’s length, not in the photograph. The radius of a counter edge; the temperature of light on stone; a channel-stitched headboard; brass inlay set into smoked oak; a drawer that closes the same way in year six as on day one. The studio draws every piece of joinery itself and details it to the room rather than buying it to fit, because that is where the difference between a good room and a resolved one is made. At Quarter31 the master bedroom is composed in Art Deco — brass inlay over smoked oak, fan-patterned wallpaper, the stitched headboard — a room with its own vocabulary that still answers to the same restraint as the rest of the house. Craft is what allows a room to have character without raising its voice.

Comfort as the test

A room can be beautiful and still fail. The test the studio applies is whether the house stays calm when the whole family is home, and whether it still reads as considered after a year of ordinary use. Comfort in this sense is not softness; it is the absence of friction — the bedside that is already there when you reach for it, the storage that means nothing is left out, the dining table long enough for the people who actually eat there. Setthasiri Donmuang, a 400-square-metre house in north Bangkok, was briefed in a single sentence — a home that feels like a luxury hotel — and the answer was not a lobby to live in but the particular calm of a good suite: cove-lit ceilings, upholstered walls, every decision already made before you enter the room.

Setthasiri Donmuang — the calm of a good suite, built into a standard developer plan.

The owner’s identity, not the studio’s

Here the phrase is most often misused. Quiet luxury is not a house-style; it is a discipline for making a house belong to the people who live in it. The Ritz-Carlton residence inherited a formal shell — classical panelling, a skyline — and answered it with family: oak and tan leather instead of showroom lacquer, a table for three generations, a nursery given the same attention as the master suite. Quarter31’s middle floor is built around the family’s own objects and a piano corner. The measure of a finished project is whether the client recognises it as made for them rather than for the studio’s portfolio. A room that looks like a magazine spread but not like its owner has failed the brief, however expensive it is.

Longevity: designed to outlast the photograph

The last decision is about time. Trend-led rooms date from the day they are photographed; the loud gesture that wins attention in year one is the thing that has to be removed in year six. Quiet luxury is a bet on the opposite — materials that age, proportions that do not go out of fashion, lighting that can be re-tuned rather than replaced, joinery that is built rather than bought. It is also the reason the studio prefers to carry a house from drawing to hand-over under one contract: longevity is decided in the details that get simplified when the concept is handed to someone else at the end of the design stage.

What this means if you are commissioning a home

If you want a house that announces itself, there are studios that do that well; this is not one of them. If you want a house that is calm on an ordinary Tuesday, that your guests cannot quite explain and that looks better in a decade than on handover day, then the seven decisions above are the brief — and the finishes, the ones most people arrive with, are the last thing we will talk about.

Condominium renovation in Bangkok: what owners should plan before design

Living, dining and kitchen in one volume with dark book-matched marble at The Bangkok Sathorn condominium

A condominium renovation is the most constrained work a residential designer does, and the most misunderstood. Owners tend to arrive with references for finishes: a stone, a kitchen, a colour. What decides whether the apartment becomes a good home is almost never on that list. It is the plan, and the plan is governed by things that cannot move. Three of the studio’s completed apartments in Bangkok — a 120-square-metre unit on Sathorn, an 80-square-metre residence at Four Seasons Private Residences on the river, and a 250-square-metre family home at the Ritz-Carlton Residences — were very different briefs. The lessons were the same.

Start with what cannot move

Every tower fixes four things before an owner has any say: the structural core and columns, the riser positions for water, drainage and air-conditioning, the ceiling height, and the location of the wet areas. A bathroom can be reworked; it can rarely be relocated, because the floor drain sits where the building put it. A kitchen can change character; its extract and drainage generally cannot cross the apartment. Ceiling height is the quiet one — a cove, a concealed curtain track and a fresh-air duct all compete for the same few centimetres, and in a compact unit the difference between a ceiling that feels generous and one that feels pressed is the order in which those decisions are made.

This is why the studio’s first drawing on any condominium is not a mood board but a plan of the unit’s fixed points, taken from the building’s own drawings and checked on site. At The Bangkok Sathorn, every wardrobe, riser and door was stacked away from the window wall so that living, dining and kitchen could read as one continuous room facing the skyline. That plan was only possible because the fixed points were mapped first and the rooms arranged around them.

The Bangkok Sathorn — living, dining and kitchen as one room along the glass; services and storage pushed to the inner face of the plan.

Decide which rooms deserve the view

In most Bangkok high-rises the view is available to two or three rooms, not to all of them. Choosing which rooms get the glass is the single most consequential decision in the renovation, and it should be made by how the household actually lives, not by the developer’s original layout. A couple who entertain will give the window wall to living and dining; a family with young children may give part of it to a room that is used at four in the afternoon. What the studio resists is the default of pushing a sofa against the glass — at The Bangkok Sathorn the sofa was pulled away from the window and turned inward, leaving a clear walking line along the view, so the skyline stays part of the room rather than a backdrop to furniture.

In a small unit, lift everything off the floor

The 80-square-metre residence at Four Seasons Private Residences set the sharpest version of the problem: a five-star address whose promise is larger than the plan can physically hold. The answer was never to decorate harder. It was to plan tighter — one floor material run unbroken from the front door to the window, storage lifted off the floor above the bed and over the wardrobe line, backlit cabinets in place of freestanding furniture, and a finish list held to a handful of materials with at most one saturated colour per room. The eye reads the room as larger than the plan says it is because the floor is continuous and the walls are calm.

Keep the material list short

Condominium interiors in Bangkok are won or lost on the plan, not on the finishes, and the corollary is that a compact apartment cannot afford variety. Across the three projects the palette was held to four or five materials each: smoked oak, bronze and pale limestone with a single dark book-matched stone on Sathorn; pale timber panelling, grey-veined stone and a deep blue cabinet line at the Four Seasons; oak, tan leather, white panelling and travertine at the Ritz-Carlton. Each apartment has one gesture — the stone wall, the lacquered wardrobe, the travertine media wall — and everything else recedes. Add a sixth material and the room starts to read as busy at a scale where busy is fatal.

Light indirectly

Downlight grids belong to offices. In each of these apartments almost all of the light is indirect — coves washing the ceiling, shelf edges lit from within, cabinets glowing behind glass — so that at night the city outside stays the brightest thing in the room. Indirect lighting also solves a renovation problem: it needs a ceiling detail that hides the fresh-air duct and the curtain track at the same time, and it makes a low slab feel taller. It has to be drawn early, because the cove and the services share the same zone.

Understand the building’s rules before you price the work

A managed tower hands over an apartment finished to a standard, not to a household, and the management office holds rules on working hours, lift bookings, waste removal, noise, deposits and which trades may enter. Those rules shape the programme as much as the design does: a job that would take one uninterrupted stretch in a house is broken into permitted windows in a tower. The studio has set out the process for branded residences in detail in a separate article, but the principle applies to every condominium: read the fit-out guidelines before the drawings are priced, not after the contractor is on site.

On a site where you cannot improvise, documentation is everything

In a house, a detail can be resolved on site. In a condominium it cannot — there is no space to store material, no tolerance for noise outside the permitted hours and a management office watching the lift. That is why the Ritz-Carlton residence was drawn to full documentation before anything was built: interior architecture, bespoke joinery drawings and a complete FF&E specification, so that the work could be priced from a finished set and the owner had a fixed picture of what 250 square metres would look like before contractors entered the building. The same logic argues for a single point of accountability. At the Four Seasons the studio delivered the residence turn-key — the practice that drew it also built it, under one contract — so that one party answered to the building rather than several arguing across a drawing.

What to bring to a first meeting

The building’s fit-out guidelines and the unit’s as-built drawings if you have them; an honest account of who lives in the apartment and at what hours; the two or three things you cannot live without, and the two or three you would happily lose. The finishes can wait. Which walls stay, which rooms get the view and how the light will work cannot.

How to choose an interior designer in Bangkok: 9 checks before hiring

Oval stone dining table, dark timber chairs and a linear alabaster pendant beside a textured feature wall at Setthasiri Donmuang

The short answer: choose the designer whose built work most resembles the project you are about to commission, who will show you a complete construction drawing set from a finished job, and who can tell you — before you sign — who will be standing on your site when something is wrong. Everything else, including awards, is secondary to those three.

Key takeaways

  • Judge built projects, not renders. A render proves an idea; a finished room proves the studio can get it through construction.
  • Ask to see a construction set, not a concept board. The drawings decide whether the design survives the contractor.
  • Decide who carries the risk on site — you, the designer, or a single accountable party — before you compare fees.
  • Awards are evidence of taste and consistency; they are not evidence that the studio has built your type of project at your scale.
  • The right designer will tell you which route — design-only, hybrid or turn-key — fits your project, including when it is not their own.

1. Portfolio relevance — the same problem, not the same style

Style is the least useful filter. A studio that has built a 400-square-metre family house, a 120-square-metre apartment in a branded tower and a nightclub has solved three different problems, and only one of them is yours. Look for the constraint that matches: a management office with a rulebook if you own a unit at a branded residence; a stair and four storeys if you are building a house; a licence and an opening date if it is a clinic. Then look at whether the studio’s answer to that constraint is visible in the finished photographs, not only described in the text.

2. Built experience — renders are not evidence

Every studio can produce a beautiful image. Fewer can show you the same room photographed after a year of use. Ask for three completed projects with photography taken after handover, the client’s permission to speak to them, and the honest story of what changed between the concept and the finished room. A studio that has built nothing like your project will learn on your site, at your cost.

3. The drawing set — where projects are won or lost

Most interiors fail in the gap between the drawing and the site. A concept board is a suggestion; a construction set is an instruction. Ask to see the drawings from a finished project: joinery details to the millimetre, lighting layouts with circuits and fittings, a reflected ceiling plan, a material and FF&E schedule that names products rather than “similar”. If the studio cannot show you a set a stranger could build from, the contractor will interpret the design, and the interpretation is where the marble becomes a similar marble.

4. Budget control — who prices the drawings, and when

Ask how the budget is set and at what stage. A price against a concept is a guess; a price against a documented design can be defended. Ask what counts as a variation and whether cost movement caused by the builder’s own sequencing or coordination is yours to absorb. The answers tell you whether the sum you agree will still be the sum you pay.

5. Material knowledge — Bangkok is not a neutral climate

A fluted wall in a shophouse that opens onto Surawong Road needs a moisture-resistant core or the profile softens in its second year. Timber on a floating villa on the River Kwai behaves differently from timber in a sealed tower. Ask a designer what they would not specify in Bangkok, and why. A good answer is specific and slightly boring.

6. Site supervision — how many phone calls

The practical test: when something is wrong at handover, how many phone calls does it take to reach the person who can fix it? On a project where the designer hands over a set and walks away, it is several, and each party blames the other. On a project where the design lead is on site through construction — with authority over substitutions written into both contracts — it is one. MU:IN was built by a contractor to our drawings with the design lead on site; the concept survived because someone who drew it was there when the ceiling was being hung.

7. Turn-key capability — and knowing when not to use it

A studio that can carry a project from drawing to opening under one contract removes the interpretive layer entirely. It is the right route when the date is commercial, when the detail is the point, or when you do not want to run a procurement process. It is not always right: a trusted builder, a tender policy, or a large simple project can favour design-only. The useful signal is whether the studio will say so. How the three routes compare is set out in interior designer vs turn-key contractor in Thailand.

8. Communication, contracts and timeline

Ask who your day-to-day contact is and whether that person will still be there during construction. Ask for the contract before you decide, and read what it says about approvals, variations, payment stages and what happens if the programme slips. Ask for a dated programme against the sum, not a duration. On a house, ask how the studio handles the moment — there is always one — when a family changes its mind about a room after the joinery is ordered.

9. Awards versus experience

Awards are worth reading for what they reward: atmosphere, sequence, light, how a room performs when it is full. They tell you a jury liked the finished work. They do not tell you the studio has built your typology at your scale, or that it will be on your site. Weigh them after the built record and the drawings, not before.

Common mistakes

  • Choosing on renders and a fee percentage, then discovering the drawing set is a concept board with dimensions.
  • Appointing a contractor before the design is documented, so the price is set against a guess.
  • Assuming “turn-key” means the same thing everywhere — for some it is a coordinator forwarding emails.
  • Treating the management office of a branded tower as a formality; the approvals set the programme.
  • Weighing awards above built projects of your own type.

A decision framework

Score each candidate on five questions, in this order: Have they built my type of project at my scale, and can I see it finished? Can they show me a construction set from that project? Who is on my site during construction, and is it in the contract? Is the price set against a documented design, with variations in writing? Will they tell me which route fits — even when it is not the one that pays them most? A studio that passes the first three is worth a conversation; one that passes all five is worth appointing.

How we work

For the record, this is how Gratitude Design answers those questions. Every project is documented to construction level — joinery, lighting, the full FF&E schedule — whether we build it or not. Ritz-Carlton Residences was design and documentation only, built by the owner’s team to the management office’s approvals. Kilik Social Club and Four Seasons Private Residences were turn-key, from bare shell to handover under one contract. Setthasiri Donmuang was design and FF&E with every piece specified and scheduled before site. We will say which route fits a project, including when it is design-only.

Interior designer vs turn-key contractor in Thailand: which route fits?

The question usually arrives in the first meeting, phrased as a choice: do we need an interior designer, or a contractor who can do the whole thing? In Thailand the honest answer is that the words describe three different ways of buying the same result, and the right one depends less on the size of the project than on who you want to be accountable when something on site is wrong. Having delivered more than fifty projects turn-key since 2015 and documented others for owners’ own builders, this is how we would explain the difference to a friend.

Where projects actually fail

Most interiors do not go wrong in the drawing. They go wrong in the gap between the drawing and the site. A design is resolved and documented, a contractor prices it, and the substitutions begin exactly where cost and effort concentrate — which is where the design lives. A specified stone becomes a similar stone; a lighting temperature becomes whatever the supplier had; a joinery detail is simplified because it was inconvenient. The owner then spends months adjudicating between a designer who blames execution and a contractor who blames the documentation, often in a language they do not speak. Both are partly right. Everything below is a way of deciding, before you start, who closes that gap.

Route one: design and documentation only

You commission the concept, the design development and a full construction set — drawings and specifications complete enough for any competent builder to price and construct without guessing — and you appoint the contractor yourself. This is the right route when you already hold a relationship with a builder you trust, when a corporate procurement policy requires competitive tender, or when the project is large and simple enough that open pricing genuinely wins. The Ritz-Carlton Residences apartment was commissioned this way: interior design, bespoke joinery and a complete FF&E documentation set, built by the owner’s own team to the management office’s approvals. The discipline that makes it work is drawing for a stranger — a set that would survive an open tender is a set that survives construction.

Route two: a contractor who also designs

Many contractors in Thailand offer design as part of a build contract, and for a straightforward fit-out it can be efficient. The trade to understand is that the design is priced as an input to the construction margin, so the drawings tend to be produced to the level the builder needs rather than the level the owner would choose, and the substitutions described above happen inside one company, where nobody has an incentive to flag them. If the detail is not the point — a standard office floor, a plain retail unit — this route is often adequate. Where the detail is the point, bespoke joinery, integrated lighting and book-matched stone are precisely what a general contractor prices as a risk and builds as an approximation.

Route three: turn-key by the studio that drew it

On a turn-key commission the studio that designed the space is the one accountable for building it: its own site supervision, its own trades for joinery, lighting and finishes, its own procurement and installation of every loose piece, styling, snagging and handover — under one contract, at a price and a date agreed before work begins. The drawings are still produced to tender standard, because that is what keeps a set honest, but the party who would have interpreted them is the party who made them. When a coordination error surfaces on site, it is ours to absorb rather than yours to arbitrate. Kilik Social Club went from bare warehouse to opening night this way, and the Four Seasons Private Residences apartment — eighty square metres in a building with its own rulebook — was handed over furnished and ready to live in on the same basis.

Kilik Social Club — one contract from bare shell to opening night; the concept survived construction because the builder was the designer.

A fourth arrangement worth knowing

Between the routes sits a hybrid the market rarely names: the studio designs and documents, a contractor builds, and the design lead stays on site through construction with authority over substitutions. MU:IN was built by King Big Wood to our documentation with the design lead on site, and it is now the studio’s most decorated room. It works when the contractor is capable and the owner wants competitive pricing without losing the concept — but it only works if the supervision is written into both contracts rather than assumed.

How to decide

Ask three questions. First, is the date commercial or aspirational — a lease running, a licence pending, a family moving — because a commercial date favours a single accountable party. Second, is the detail the point? If the answer is yes, the interpretive layer is your biggest risk and turn-key removes it. Third, when something is wrong at handover, how many phone calls should it take to reach the person who can fix it? On a turn-key project the answer is one.

Whichever route you choose, insist on two things: a documented design before anyone prices it, and variations quoted and approved in writing before the work is done. The agreed sum should move only when you change the scope. Cost arising from the builder’s own buying, sequencing or coordination should be theirs to absorb — and the contract should say so.

Private club design in Bangkok: 5 lessons from Kilik and MU:IN

Warehouse bar interior with exposed steel trusses, arched back bar and colourful lounge seating at Kilik Social Club, Bangkok

Two of the most decorated rooms this studio has built are, on paper, opposites. Kilik Social Club is a 280-square-metre warehouse in Phrom Phong that opens as a night garden — timber trusses, a painted forest, live jazz and deep seating. MU:IN is a nightclub in Thonglor that reads as polished metal and moving light, with a domed LED ceiling and a dance floor at its centre. One is warm and low; the other is fast and bright. Between them they have collected ten international awards. And having drawn, built and opened both, we can say that they were designed from the same five decisions, made in the same order, before a single material was chosen.

1. One room, or several — decide before the plan

A private club has to do two contradictory things at once. It has to feel like one crowd on a full Saturday, and it has to hold a table of six who have paid for privacy and do not want to be part of that crowd. The two projects answered differently, and both answers were correct for their brief. Kilik put the whole evening into a single volume: bar, lounge and stage share one room, so a table booked at seven is still the best seat in the house when the band starts at ten, and the only enclosure is a private lounge for twenty on the mezzanine, looking down over the stage through iron balustrades. MU:IN chose separation over compromise: an energetic dance floor at the centre, VIP lounges held apart from it, and a second room — JACK, framed by a lacquered gate — that lets a party change register without leaving the building.

The lesson is not that one model is better. It is that the choice has to be made first, because it decides the section, the acoustics, the service routes and the licence, and none of those can be corrected with upholstery later.

2. Light is the material, not the finish

In daylight retail, the finishes carry the room and the lighting reveals them. In a club it is the reverse. At MU:IN, lighting is the primary instrument: geometry and reflection do the work, and the room’s character changes across the night rather than holding one setting — a graphic ceiling of light over the twin escalators on arrival, a woven-steel portal, then the domed ceiling in full performance. The polished metal and textured surfaces were specified for how they behave under moving light, not for how they photograph at noon. Kilik works the same principle at a lower temperature: a ribbon of amber light set into the live-edge counter lights drinks and hands rather than the room, the back bar is a row of lit arches with the spirits as the display, and hand-dyed organza floats above the counter to soften the steel roof without a single ceiling work.

Practically, this means the lighting design starts with the plan, not after it, and that the budget for control — dimming, scenes, the ability to move from seven o’clock to midnight — is protected from the first cost review.

3. Arrival is a sequence, not a door

Both clubs are judged on a Saturday, not in a photograph. Several hundred people have to move past a door, a cloakroom, a bar and a washroom without the queues meeting, and the room has to feel full at eleven and not empty at nine. MU:IN’s arrival is a deliberate sequence — escalators rising through light, the corridor that announces the club before a drink is poured, and only then the hall. Kilik’s front elevation was rebuilt as a lattice of stacked brick so the building signals craft from the street, and the plan inside runs from the door to the stage on a single clear line. In each case the first thirty seconds were designed as carefully as the bar.

4. Acoustics decide whether people stay

Live music and a DJ set make opposite demands, but both come down to the same measure: can the table beside the stage hold a conversation, and can the back sofa still feel the band. At Kilik the warehouse height takes the energy of the room upward while planting, upholstery and soft layers pull reverberation down to conversation level; the upstairs private room is one wrapped space that can hold a party without leaking it into the club below. At MU:IN the separation of rooms does the acoustic work that soft finishes cannot at nightclub sound levels. Neither venue would have worked with the acoustic brief left to the sound contractor at the end.

5. Build it as one commission

Kilik was delivered turnkey — bare shell to opening night under a single contract — and MU:IN was built by King Big Wood to the studio’s documentation with the design lead on site. In both cases the value was the same: every trade-off during construction was resolved by the designer rather than against the design. This is the point at which most hospitality interiors quietly lose their concept — the greenery thins, the joinery simplifies, the lighting flattens — and it is the reason the studio prefers to carry a bar or club from drawing to opening rather than hand over at the end of the design stage.

What the awards were actually for

MU:IN has been recognised seven times across three continents between 2024 and 2026, including the Architecture Master Prize, Golden Pin, the IDA Design Awards, the Kyoto Global Design Award, the OPAL Awards London, the Luxury Lifestyle Awards and the LIV Hospitality Design Awards. Kilik holds the German Design Award and Iconic Design Award 2025 and a LIV Hospitality Design Award. Read the citations and none of them mention a finish. They describe atmosphere, sequence, light and how the room performs when it is full — which is to say, they reward the five decisions above. The full record is on Awards & Press.

If you are planning a bar, club or members’ venue in Bangkok, bring the licence, the covers you need to make the numbers work, and an honest description of your Saturday. The materials can wait; the five decisions cannot.

Branded residence fit-out in Bangkok: building rules and owner checklist

Panelled living room with a travertine media wall at the Ritz-Carlton Residences Bangkok by Gratitude Design

A branded residence — a unit at The Ritz-Carlton Residences, Four Seasons Private Residences, or any tower run to a hotel operator’s standard — is handed over finished. The floors are laid, the bathrooms are fitted, the kitchen is in. It is also handed over with a rulebook. Between the day you receive the keys and the day the apartment feels like yours sits a management office whose job is to protect the building, and whose rules decide what a fit-out can be. Having designed and documented several of these apartments, this is what owners should know before they start.

Ritz-Carlton Residences Bangkok — the developer’s panelled shell kept intact; everything inside it designed, drawn and delivered within the building’s rules.

The shell is not yours to change

The first thing to accept is that the envelope belongs to the building. Windows, façade, balcony rails, the front door, and usually the corridor-facing wall are common property and cannot be altered. Structural walls and floor slabs are off limits, and so — more often than owners expect — are the fire-rated partitions between units and the ceiling zone that carries sprinkler heads and smoke detectors. A design that begins by asking to move a sprinkler will spend its first two months in correspondence. A design that treats the shell as a given and works inside it begins on site much sooner.

What the management office will ask for

Every branded building has a renovation application, and most of them ask for the same things: a full set of drawings, a scope of work, a schedule, the contractor’s insurance and registration, and a deposit held against damage to the common areas. Some also require a review by the building’s own engineer for anything touching plumbing, electrical loads or air-conditioning. The application is not a formality. It is the moment the building decides whether your contractor is allowed in, and an incomplete submission is the most common reason a project loses a month before it starts.

Working hours, lifts and noise

Residents are living either side of you, so the building controls how and when work happens. Expect a fixed working window — typically weekday daytime hours with a hard stop, and no work on weekends or public holidays — with a separate, shorter window for anything noisy. Material deliveries go through a service lift that has to be booked in advance and is shared with every other unit under renovation; large items such as stone slabs or a single-piece dining table may need a specific delivery slot and floor protection along the entire route. Waste leaves the same way. A programme that ignores these constraints is a programme that will be wrong.

Why documentation matters more here than in a house

In a private house, a decision missed on the drawings can be made on site. In a branded residence it usually cannot — the contractor is on the clock inside a narrow window, the lift is booked, and every change of mind has to go back through the office. This is why we treat the drawing set as the project. Interior architecture, bespoke joinery shop drawings, lighting and electrical layouts, and a complete FF&E schedule are issued before a single trade arrives, so that pricing is fixed, approvals are obtained once, and the site period is as short as the building will allow. Our work at Ritz-Carlton Residences and Four Seasons Private Residences was carried through in exactly this way: full documentation first, then a contractor’s programme built around the building’s calendar.

Where the design freedom actually is

None of this limits the result as much as it sounds. The freedom in a branded residence lies in everything the hand touches: wall finishes and panelling, the ceiling within the permitted zone, built-in joinery, lighting design, stone and timber floors laid over the existing screed, and the loose furniture. At The Bangkok Sathorn a single run of book-matched marble was carried from behind the television into the kitchen to hold three functions in one volume — a transformation of the room made with no change to the plan. The shell sets the frame; the interior is still entirely a design decision.

Services: what can move and what cannot

Every branded tower fixes its services before an owner arrives, and the fit-out has to be planned around them rather than against them. Drainage is the least negotiable: the floor drains for bathrooms and the kitchen sit where the building put them, so a bathroom can be re-planned inside its footprint but rarely moved across the unit, and a kitchen can change character but seldom position. Air-conditioning is the second constraint — fan-coil units, condensate drains and fresh-air ducts occupy a fixed ceiling zone, and any new cove or dropped soffit has to be drawn around them. Electrical load is the third: the unit has a set capacity, and a design that adds a wine cabinet, a steam shower and a full lighting-control system needs the building’s engineer to confirm the supply before it is priced. In our Four Seasons residence the plan accepted every one of these points and put the effort into what could move — storage lifted off the floor, a single floor material end to end, light concealed in the existing ceiling zone — which is why an 80-square-metre unit reads as larger than its plan.

Built-ins, furniture and the service lift

Built-in joinery in a branded residence is governed by two things most owners never think about: what may be fixed to the walls, and what will physically fit into the building. Party walls and corridor walls are often fire-rated, and the management office will restrict what can be fixed to them and how; wet-area walls carry waterproofing that must not be pierced. Joinery is therefore drawn to be self-supporting or fixed only where the building allows, and it is designed in sections that pass through the service lift and along the corridor — a wardrobe wall arrives as flat-packed carcasses and is assembled in the room, never craned or carried up the stair. The same rule decides the loose furniture. A long dining table or a large sofa is measured against the lift car, the corridor turn and the front door before it is chosen, and a piece that will not pass is redesigned in two parts or built in place. At the Ritz-Carlton Residences every joinery piece and every loose item was drawn, scheduled and checked against the route into the building before it was ordered, which is what let the site period stay inside the calendar the office had approved.

Lighting and art in a finished ceiling

The ceiling in a branded residence is delivered finished and already carries sprinkler heads, smoke detectors and the air-conditioning grilles, none of which can be moved without the building’s engineer. Good lighting is still possible — it is simply planned as coves, concealed lines in joinery and a small number of adjustable fittings within the existing zone, with the sprinkler layout drawn onto the ceiling plan from day one so that no cove or pendant lands on a head. Dimming and scene control are wired inside the unit and do not touch the building’s systems. Art needs the same forethought: heavy pieces cannot be fixed into fire-rated or waterproofed walls, so a hanging rail or a joinery-backed wall is drawn where the collection will live, and large canvases are checked against the lift and corridor exactly like furniture. Where the building permits it, we set out a hanging system in the drawings rather than leaving the walls to be drilled after handover.

A checklist before you commission

Ask the management office for the renovation guidelines and application form before appointing anyone. Confirm the working hours, the lift-booking procedure and the deposit. Find out whether the building requires its own engineer’s review, and for what. Then appoint a designer who will produce a complete documentation set rather than a concept, and a contractor who has worked in a comparable building before. Do those five things in that order and the apartment will be finished in one continuous site period, which in a building full of neighbours is the outcome that matters most.

How to make a house feel like a luxury hotel: 5 design decisions

“We want it to feel like a hotel” is the most common sentence we hear at the start of a residential project in Bangkok. It is also the most misunderstood. Clients rarely mean the lobby, the marble, the double-height everything. What they remember from a good hotel is the room — the first minute inside the door, when everything has already been decided and nothing asks anything of you. That feeling can be built into a house. It comes from five decisions, none of which is about ornament.

Setthasiri Donmuang — a hotel arrival compressed into a family entrance: pattern on the floor, height above, and one deliberate lighting gesture.

1. Sequence the arrival

Hotels are designed as a sequence: porte-cochère, lobby, lift, corridor, door, room. Each step is calmer and more private than the last. A standard developer house has no sequence at all — the front door opens straight into the living room, and the living room is also the corridor. The first decision is to give the entrance a threshold of its own: a change of floor material, a step in ceiling height, a piece of furniture that says “arrive here”. At Setthasiri Donmuang the foyer was given two storeys and a chequerboard marble floor so that coming home registers as an event before the house reveals itself. In an apartment the same effect is achieved with less: at Four Seasons Private Residences the entry is treated as a short gallery — marble floor, timber portals, one long sightline that ends at the window.

2. Step the materials down from public to private

A hotel’s public floors are hard and polished — stone, glass, lacquer — because they have to survive traffic and photograph well. The rooms are soft: carpet, upholstery, linen, timber. The transition happens in the corridor. A house can follow the same logic. Ground floor in darker, more reflective finishes where guests are received; upper floor stepping down to lime-washed oak, woven panels and fabric-wrapped walls where the family actually lives. The house reads as one design because the palette is continuous, but the temperature changes floor by floor, and the bedrooms feel like suites rather than rooms.

A master suite planned on hotel logic: the bedside is built in, the wall behind the bed is lit rather than decorated, and every surface the hand meets is soft.

3. Build the bedside in

The single detail that most separates a hotel bedroom from a domestic one is that nothing in it is loose. The bedside table is part of the headboard wall; the lamp is fixed; the switches, the charging point and the shelf for a glass of water are exactly where the hand expects them. This is joinery, not furniture, and it has to be drawn — which is why we treat the headboard wall as a piece of architecture in every residence we design. Once it is built in, the room needs almost nothing else, and that emptiness is what reads as luxury.

4. Light the walls, not the ceiling

Walk into a good hotel room at night and you will struggle to find a downlight. The light comes from coves, from behind panels, from under shelves, from a lamp beside the bed. The ceiling stays dark and the walls glow, which makes the room feel taller and the occupant look better. This is the cheapest of the five decisions to specify and the most often lost on site, because it requires the ceiling, the joinery and the electrical drawings to agree with each other. At Ritz-Carlton Residences the living room is lit from a continuous cove with not one visible fitting — a rule we hold to in every bedroom we draw.

5. Give the dressing room its own door

Hotel suites separate sleeping, dressing and bathing into three rooms, however small. Most houses put the wardrobe in the bedroom, which means the bedroom is also a changing room, a storage room and, at seven in the morning, a shared corridor. Moving the wardrobes into a dressing room — even a corridor two metres wide, lit from under every shelf — is the decision that most changes how a couple lives in a house. It also lets the bedroom itself be almost empty, which returns us to where we started.

A dressing room detailed like a boutique fitting room — the daily routine given a room of its own.

What it is not

None of the five decisions involves a chandelier, a logo, or a lobby-scale gesture in a family living room. The hotel feeling is planning and lighting, not decoration. It is also why it survives daily life: a built-in bedside does not get moved, a cove does not get replaced, a dressing room does not wander back into the bedroom. Get the sequence, the material temperature, the joinery, the light and the dressing room right, and the house will feel like a hotel on a Tuesday evening in five years’ time — which is the only test that matters.
