The standard list of questions a client asks an architect — who does the work, what the fee is, how long it will take — still applies at the top of the residential market. But a luxury home commissions a different kind of relationship, and the questions that protect that relationship are different too. The build will run three to five years. The figures involved will not be public. The trades and suppliers required to do the work well are a small, specific group. And the day the project is finished, you will be living in the result.
These are the questions we would put to a practice before signing on a project of this kind.
Who, specifically, will be in the room at month thirty-four?
A house at this scale typically takes three to five years from first meeting to handover. Practices change in that time. People leave, teams reshuffle, principals take on other projects. Ask, at the first meeting, not just who is doing the work today, but who will still be doing it in year three. The right answer is specific: the principal you are meeting will be the one on site at handover, and the project will not be quietly passed to a more junior team after the design phase. If the practice cannot promise that, the experience you signed up for is not the one you will get.
How often will you actually be on site during construction?
For a standard residential build, weekly or fortnightly site visits are common. For a luxury build with hundreds of custom elements, that is the floor, not the ceiling. Ask about the cadence directly. Ask what happens when a bespoke piece is being fabricated off-site — will the architect review it at the joinery shop, or only when it arrives on the floor? The difference between those two answers is the difference between a finished piece that arrives correct, and one that arrives correct after the second attempt.
Which trades and suppliers have you worked with at this level before?
Luxury residential is built by a small ecosystem of trades — particular joiners, stonemasons, metalworkers, glaziers, plasterers — most of whom take on a limited number of projects each year. A practice that has built at this level will have working relationships with these people, know which ones can deliver to specification, and know which ones cannot. Ask for names. A practice that hesitates, or that suggests you appoint your own trades from scratch, is one whose previous work at this scale has been more limited than the portfolio implies.
What does your insurance cover, at what limit?
At a $5 million build cost and above, the financial exposure of any single error rises sharply. Professional indemnity insurance limits become a real consideration. Ask what the limit is. Ask whether it covers the full construction value of the project, and whether the practice can increase the cover for this specific commission if needed. This is a question a serious practice will answer in concrete numbers, not generalities.
How do you handle confidentiality and publication?
Luxury residential commissions are, almost by definition, private. Many clients prefer the project never be published — no photography, no awards submissions, no website portfolio listing. Others are happy for the building to be published, but only without identifying the location or the owners. Ask, openly, how the practice handles this. A standard contract should include clear clauses on confidentiality and publication rights, and the practice should walk you through what they expect at handover. A practice that has not thought about this is one that may not have built privately at this scale before.
Can we visit a completed project of yours, by appointment?
The most useful reference at the luxury end is not a phone call. It is an hour spent walking through a finished building of comparable scope, with the owner present and the architect not. Many practices will arrange this for a serious prospective client, subject to the previous owner's consent. The way that owner speaks about the practice — the small details they mention, the moments they remember as difficult, the way they describe the architect's presence on site — is more useful than any portfolio page.
What happens if we are not in the country for parts of the project?
Many clients of luxury residential projects travel often, or live partly elsewhere. A four-year project will inevitably include periods where you are not available for site meetings, sample reviews, or live decisions. Ask how the practice handles this. The right answer involves a clear protocol — decisions queued for your return, a defined set of decisions the architect can make on your behalf, a regular update cadence that does not depend on your physical presence. Without that protocol in place, the project will either stall or drift away from the brief.
Which consultants do you expect to engage, and have you worked with them before?
A luxury residential project will typically engage a structural engineer, a hydraulic engineer, a landscape architect, a lighting designer, an acoustic consultant, and often an AV integrator, a security consultant, and a heritage or planning specialist. Each of these adds to the project fee and to the coordination required. Ask which consultants the architect proposes to bring in, and which they have worked with on previous projects of this scale. An established team works faster, communicates more cleanly, and produces better-resolved work than one assembled for the first time on your house.
A closing note
These questions are not designed to test the practice. They are designed to surface the working assumptions that will shape the next four years. A practice that has done this kind of work before will answer them quickly and specifically. A practice that has not will answer in generalities. Either is useful information.
The right relationship at this scale is built on a small number of very direct early conversations. The questions above are most of them.
