Owners ask for a date the way they ask for a price, and the answer deserves the same honesty: a well-run residential project has a sequence with a logic to it, and the total depends less on how fast anyone works than on how many decisions are made early, how much has to be made by hand, and what the building allows. What follows is that sequence as the studio runs it, stage by stage, with the things that stretch or shorten each one. We have deliberately left out week counts; a number given before the brief and the site are known would be a guess dressed as a promise.
Stage one — brief and survey
Every project begins with two conversations and one measurement. The first conversation is about how the home will be used on an ordinary day — who cooks, who works from home, where the children are at four in the afternoon, what the household cannot live without. The second is about scope and route: a full re-plan or a fit-out, design-only or turn-key. The measurement is the site survey, which in a condominium means recording the fixed points — risers, drains, ceiling heights, sprinkler and detector positions — and in a house means the structure, the roof and the ground. This stage is short when the owner arrives with a floor plan, the building’s fit-out rules and a clear account of the household, and long when the brief keeps changing. It is the cheapest stage in which to change your mind, and the last one in which changing it costs nothing.
Stage two — concept
The concept fixes the plan and the idea before a single finish is chosen: which rooms get the view, where the volume is spent, how the household moves through the home, and the material temperature of each room. At Quarter31 the concept decided that a double-height living room would be given exactly three things to do with its height and everything else would be held to furniture scale; at The Bangkok Sathorn it decided that living, dining and kitchen would read as one room and that every wardrobe, riser and door would be stacked away from the window wall. Once an owner approves a concept, the plan is settled. Reopening it later is the single most common reason a residential programme slips, because everything downstream — joinery, lighting, services — is drawn from it.

Stage three — design development
Here the concept becomes rooms: joinery designed piece by piece, the lighting plan drawn around the ceiling’s fixed points, materials and finishes selected and sampled, bathrooms and kitchens resolved to the tile. This is the stage where the material list either stays short or grows, and where lead times begin to matter — a stone slab selected from a yard, a European kitchen system, a bespoke piece of furniture, each with its own clock. The studio’s discipline of four or five finishes per home is as much about time as about calm: every additional material is another supplier to co-ordinate and another delivery to wait for.
Stage four — documentation and approvals
On a well-run project, documentation is the project. Interior architecture drawings, joinery shop drawings, lighting and electrical layouts, plumbing where it changes, and a complete FF&E schedule are issued as one set, so that the work can be priced from a finished picture and built without improvisation. In a condominium this set is also the renovation application: the management office reviews it, the building’s engineer may comment on anything touching services, and the contractor is admitted only when it is approved. This stage is where a condominium and a house diverge most. A house can move to site as the set is completed; a managed tower waits for the office, and an incomplete submission is the most common way to lose a month before anything starts. The Ritz-Carlton residence was documented in full — every surface, fitting and loose item drawn and scheduled — before the building’s calendar was booked, which is what kept the site period inside it.
Stage five — construction
Construction time is governed by three things: the scope, the site and the sequence. A full re-plan with new ceilings, new services and joinery throughout takes longer than a fit-out over a developer’s finished shell. A managed tower works only in permitted hours, moves everything through a booked service lift and stops for noise restrictions; a house works continuously but exposes structure and weather. And the sequence matters more than the pace: joinery, stone, lighting and landscape arrive from different trades, and a project that has to wait for one of them stalls entirely. Turn-key delivery exists largely to hold that sequence — one party carrying the programme from bare shell to the last cushion, as at Quarter31 and the Four Seasons residence. On a design-only commission, the owner’s contractor carries it, and the owner carries the co-ordination.

Stage six — fit-out, installation and handover
The last stage is often underestimated. Loose furniture, lighting fittings, curtains, rugs and art have their own lead times, some of them longer than the construction that precedes them, and the studio orders them during design development precisely so that they land as the site finishes rather than months after. Installation is followed by snagging — the walk-through in which every drawer, hinge and dimmer is tested — and by a period in which the home is styled and photographed. A handover that feels calm is one in which nothing is still on order.
What actually makes a project longer
In our experience the programme is stretched by five things, in roughly this order: decisions reopened after the concept is approved; a material list that keeps growing; an incomplete or late renovation application in a managed building; a single long-lead item — a stone, a kitchen, a piece of furniture — that nobody ordered early enough; and co-ordination between separate parties on a design-only commission. None of these is about the speed of the work. All of them are about when decisions are made and who is accountable for the sequence.
And what makes it shorter
The mirror image. A complete brief and the building’s rules at the first meeting; a concept approved and then left alone; a short material list; documentation finished before pricing; long-lead items ordered in design development; and one party carrying the programme. A luxury home does not have to be slow. It has to be decided early.
What to bring to a first meeting
A floor plan if you have one, the building’s fit-out guidelines if it is a condominium, a date that matters to you — a move, a birth, a lease ending — and an honest account of how the household lives. With those, the studio can tell you which route and scope your date can support, and what would have to change if it cannot. A first meeting costs nothing and commits no one.
