Your next scheme,
designed not to fail.

Margins on small residential schemes are made — or lost — long before the contractor arrives on site. A poorly considered layout, a planning strategy that doesn't hold up, a tender package with gaps — these are architecture problems. We solve them.

​

We work with small developers on HMO conversions, planning uplift and residential schemes between 2 and 15 units. We think commercially from day one, because we understand that design quality and financial performance aren't in tension — they're the same thing.

Selected development projects

We're appointed at different stages depending on where you are — from testing a site's potential before you commit, to taking a consented scheme through to a package builders can price without calling you every week.

Ways we can support you

1

Feasibility & Planning

Know what a site can deliver before you commit.

 

We test layout options, planning strategy and scheme viability — so the architectural case is built to protect your position, not just satisfy the planning officer.

​

2

Technical Design

From planning consent to a fully coordinated Stage 4 package. Detailed enough to tender cleanly, coordinated well enough to build without surprises. This is where poorly managed architecture eats into contractor contingency and eventually into your margin.

​

3

PD & Compliance

Statutory Principal Designer appointment, managed properly. Compliance gaps discovered late are expensive.

 

 

We coordinate the design-phase paper trail so they don't become your problem on site.

What developers value in our approach
Have a site? Send it over.

We'll tell you what we think is possible and whether we're the right fit — in a 15-minute call, no obligation.

Working on something? We'd love to hear about it.
