How we work  ·  8 stages  ·  18–36 months

From the first conversation to the second year in.

A residential project is a long collaboration. We’ve broken ours into eight stages, with the time, fee structure and decisions each one asks of you written down. So nothing arrives as a surprise.

The studio

The same people, from first conversation to last snag.

Our process is built around a small team and long projects. The people you meet at the first conversation are the people drawing your house, walking the site with the builder, and sitting at the table when you sign things off.

Around eight projects run through the studio at any one time. Phil is on every one, every week.

Fees

How we charge.

A fixed fee for feasibility, so you know the cost of finding out. Then a percentage of the construction cost for everything after — paid in stages, against work delivered.

Feasibility
Fixed fee

Agreed up front. Includes survey and brief.

Concept → Tender
% of build

Scaled to budget. Typical range 9–13%.

On site → Year 2
% of build

Includes contract administration and first-year return visits.

Frequently asked

The questions people ask first.

Q.01
How long does a whole-house project take, end to end?

Eighteen months to three years is typical, from first conversation to moving in. Planning is the variable that swings it most.

Q.02
What do you charge?

A fixed fee for feasibility (so you know the cost of finding out), then a percentage of construction cost for everything after. Percentage scales down with budget — bigger projects pay a smaller share.

Q.03
Can we start construction before planning is granted?

Almost never, and we won’t advise it. Internal work to an unlisted house can sometimes begin under permitted development; we’ll tell you honestly when it applies.

Q.04
Do you work outside London?

Yes — about a third of our work is outside the M25. We charge travel at cost and visit weekly when on site.

Q.05
What’s the minimum project size?

Construction budgets from roughly £1m and up. Smaller projects are usually better served by someone closer to the work.

Q.06
Can you recommend a contractor, structural engineer or interior designer?

Yes. We keep a short list of people we’ve worked with for years. We’ll always tender between three.
