For more than three decades, Gregory Phillips Architects has built a multi-award-winning reputation in contemporary residential architecture, with roots in Mayfair itself, the practice was based on Savile Row for over a decade before moving to our current studio in Holborn.
We’ve worked on listed houses in South Audley Street and around Grosvenor Square, alongside contemporary new build and modernisation projects elsewhere in Mayfair.

Architects in Mayfair
Mayfair’s listed houses and grand townhouses sit within one of the most tightly regulated parts of the City of Westminster, and getting a project through planning here depends on demonstrating real sensitivity to that historic fabric.
We’ve worked on listed properties in South Audley Street and around Grosvenor Square, handling the particular constraints of Mayfair’s most historic addresses while introducing contemporary living to the interiors. Alongside this heritage work, we’ve also carried out contemporary new build and modernisation projects elsewhere in Mayfair.
Our own history in the neighbourhood runs deep, the practice was based on Savile Row for over a decade before relocating to our current studio in Holborn, and that familiarity with Mayfair’s streets and its planning department has stayed with us.
Whether it’s a heritage renovation or a contemporary new build, we work with a trusted network of consultants, craftsmen and suppliers who understand the standard Mayfair demands.
In Mayfair, our studio offers the full range of architectural services, with involvement from concept design and planning consents through to construction information and house styling.
