The personal attention of a small studio, with the technology of a large practice — and the experience to know what your council will approve before you commit.
Big firms have the tech but treat you like a number. Tiny outfits give attention but feel risky. We are the rare combination — and each part answers a real worry.
Before you commit, we tell you what your council will actually pass — drawing on years of decisions at the boroughs we work in. You start with a realistic design, not a gamble.
We survey your home ourselves — never subcontracted — capturing it with a millimetre-accurate 3D laser scan. The same person who measures your home is the one who designs it, so nothing is lost in handoff and the design fits how you really live.
Experience your extension in VR before anything is signed off, with 3D renders that make the design real. The clarity of a large practice, without the conveyor belt.
Every project below is a real consented application — council, type, reference and decision date, so you can check it yourself. Filter by project type to find work like yours, or by council to see what we’ve done near you.

The planning process feels opaque. It needn’t. Here is exactly how we work, what’s included, and where fees fall — agreed upfront, never by surprise.
A free 30-minute call to find out what your council will realistically allow — followed by a written feasibility report on your home.
We visit and measure your home ourselves — never subcontracted.
Walk through the design in VR and sign it off before anything is submitted.
We prepare, submit and manage the full application with the council.
We see it through to decision and ready your building-regs package.
We design the extension and secure the permissions — we don’t build. Our fee is for that work, quoted as a fixed price after the first call, with the stages above made clear. Council application fees are separate and paid directly to the council.
The bigger questions — our approved work and exactly how we’re paid — are answered in full above. These are the rest.
Yes — it’s routine. Reading a council’s specific requirements and knowing what they’ll approve is exactly the job, and we’ve now done it across 61 of them. Your area is almost certainly one we can navigate.
See the approved workAbout 9 in 10 of our applications are approved first time. If a council does refuse, we talk you through the reasons and — where the scheme can be reworked to meet their objections — prepare and submit an amended application free of charge; you only pay the council’s resubmission fee. It’s why 99% ultimately get consent.
How it worksMost householder applications get a decision within about eight weeks of validation; the design and drawings beforehand typically take a few weeks more. We’ll give you a realistic timeline at the very start, not a hopeful one.
See the full processYes. Planning permission and building-regulations approval are separate consents — we can prepare and submit both, so you’re covered from the first design through to construction-ready drawings.
What’s includedYes — we’ve had schemes approved in conservation areas, supported by heritage statements where needed. Listed buildings require listed-building consent alongside planning, which we handle too.
See conservation-area approvalsMany extensions fall under permitted development and need no planning application at all. We’ll tell you honestly which route applies before you spend anything — and prepare a lawful-development certificate if that’s the cleaner path.
How it worksBook a free 30-minute consultation. We’ll tell you honestly whether your plans are likely to pass — then follow up with a personalised feasibility report on your home: your council’s recent decisions, what’s been approved nearby, and a straight read on your chances.
And if a council ever refuses, we rework and resubmit free — you only pay their fee.
