Architect-led home renovations and extensions across North and East London.

We create homes you’ll love waking up in.

Our Process

The Design to Budget Approach

Nobody wants to compromise on their dream home. But that’s what happens to most homeowners: months spent shaping a design they love, planning permission secured, and only then do the real costs show up … and numbers that don’t match the budget they had in mind.

We built Design to Budget so that choice never has to happen. It prices your project in detail during the design stage, so you know your real build costs months before construction starts, not after you’ve already fallen for a design you can’t afford. Available with our design and build service.

About us

Get to know us

We’re known for bringing a fresh, sometimes quirky approach to reimagining period homes blending contemporary flair with a deep respect for original character. Our work strikes a careful balance between old and new: thoughtful, playful, and never afraid of statement colour or bold design details. We’re Federation of Master Builders award-winning and we have just won our 10th Best of Houzz award in 2026.

We don’t follow design trends for their own sake, instead, we approach each home on its own terms, creating spaces that feel naturally light and open, or calm and atmospheric, depending on what suits it best.
