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

Design decisions made to protect margin, not win awards

Planning strategies that anticipate objections before they're raised

Tender packages builders can price on first issue

One point of contact from first call to handover

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.
