Most clients arrive expecting their project to take less time than it will. Not because they are unreasonable, but because the architectural phase is the part that is hardest to see from the outside. The build is visible — the slab, the framing, the cladding — and so the time it takes to build feels like the whole timeline. The work that comes before it is quieter, and almost always longer than expected.
The shape of a typical residential project
For a new house in Australia or New Zealand, a realistic timeline from first conversation to handover is eighteen to thirty months. Renovations and adaptive-reuse projects sit a little shorter — usually twelve to twenty months — though small interior fitouts can move from brief to opening in six to nine.
That figure breaks down, very roughly, as follows. Discovery and feasibility take two to six weeks — a site visit, brief development, and an honest read on whether the project as imagined is buildable for the budget. Concept design, where the plan, the form and the way the building sits on the site are resolved, takes six to twelve weeks. Developed design — materials, structure, the first cost estimate against real drawings — is another eight to sixteen weeks. Documentation and council, which is the bulk of the architectural time, runs three to nine months. Tender and contract is four to eight weeks of builder pricing, negotiation and execution. Construction, finally, is nine to eighteen months for a new home, depending on size, site access, and the builder.
The slowest phase, almost always, is council. We can shorten the others by working efficiently; the planning timeline is largely outside our hands.
Where time gets lost
In nearly every project that runs long, the time is lost in one of three places. The first is the brief. Projects that begin with a vague brief — something modern, something quiet, four bedrooms — almost always require revisiting the early concept work later, when the client realises what they were really asking for. The second is decision speed. A small selection of clients can take six months to choose a stone benchtop. A project paused waiting for a client decision is still incurring time, just not architectural time.
The third is scope creep — the kitchen turning into a kitchen-and-laundry, the laundry into a laundry-and-mudroom, the single-storey concept growing a second level. Each addition is small. Together, they can push a project six months past its original timeline.
What we ask of clients
When we begin a project, we ask three things that, more than anything else, keep the timeline honest. First, an early conversation about budget — a real number, not an aspirational one. Second, a willingness to commit to decisions as they are made, rather than reopening them at documentation. Third, patience with the council phase. We can submit a clean, well-prepared application; we cannot accelerate the queue it joins.
A note on commercial work
Commercial fitouts, hospitality projects and small workplace works move faster than houses, often considerably so. A retail interior can be designed and built in twelve to twenty weeks; a restaurant fitout in twenty to forty. The compressed timeline reflects the way landlords and operators run them — usually against a fixed opening date that the construction program is built backwards from. We tend to think of these as a different kind of project, one where the architectural discipline is to subtract rather than add.
Time as the design choice
The best buildings we have worked on were not the fastest. They were the ones whose clients understood, from the beginning, that the time spent on the architectural phase was the time the building took to become considered. A house designed in three months and built in twelve will read, for the rest of its life, as a house designed in three months. The discipline of architecture is, in some part, the discipline of giving the work the time it needs.
