Sustainable Extensions & Whole-House Retrofits in London

At Studio CMA, we specialise in sustainable architecture for London homes, with a focus on sustainable extensions and whole-house retrofits that respect the character of existing buildings while dramatically improving comfort, performance, and value. This page showcases a selection of our completed projects, from sensitive upgrades to period properties to bold low-energy new builds.

Whether we’re opening up a Victorian terrace with a light-filled rear extension or delivering a deep retrofit to near Passivhaus standards, our work is rooted in thoughtful design, rigorous detailing, and a commitment to long-term sustainability. These case studies reflect our belief that architecture should work harder for homeowners, communities, and the climate.
