Residential Heritage

The Conservation and Restoration of Heritage Homes for Present Day Living

Our experts have extensive experience in residential projects varying from large-scale, complex, multi-occupancy, new developments to one-off domestic residences and major extension works.   Our teams have developed expert knowledge in the care, repair and adaptation of historic residential buildings and designing new buildings at historically sensitive sites.

Whether designing purpose-built dwellings or adapting existing buildings to accommodate domestic life, we balance historical preservation with sensitive adaptation to deliver beautiful homes that cherish classical design and embrace modern-day living.  Our pragmatic approach to design means every project must proceed in accordance with its particular set of requirements and imperatives.  When working on listed buildings or conservation areas, we aim to respect and retain historical features and supplement them with contemporary interventions, where appropriate.

Our team understand the challenges of maximising the potential of heritage residential while working within the tight constraints of an urban environment.  We have designed many new basements and roof expansions above and below for fine historic homes in Kensington & Chelsea, Mayfair, Belgravia, Fitzrovia, Westminster and other prominent locations.
