Looking to renovate your London home?

As both architects and a construction practice under one roof, we can manage every stage of your project — from concept to completion — with clear budgets, realistic timelines, and seamless collaboration. Whether you’re planning a sustainable retrofit, a beautiful extension, or a full home refurbishment, we make the process straightforward, stress-free, and tailored to how you want to live.

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 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.

Our Ethos

Our philosophy is simple: great design and great delivery should always go hand in hand.
