Basement Excavations Architects

Gregory Phillips Architects have designed basement conversion projects adding space and value to homes throughout London and the UK. We provide a unique, considered and professional approach to high quality residential design and have a track record of successful consents for basement projects throughout London, including Camden, Westminster, Kensington & Chelsea and Islington.


A basement conversion can add value and additional space to your home, with our knowledge and experience we can advise on how best to approach your conversion taking account of key considerations such as local planning policy and technical and structural requirements. Additional considerations such as tree root protection zones and positioning and arrangement of lightwells should also be taken into account where appropriate.


Drawing upon an established and trusted network of structural engineers, arboriculturalists, planning consultants, landscape designers and other suppliers we have the ability to project manage all elements of a basement construction project from inception to completion.

We have produced many award-winning projects for both architecture and interior design; our most recent works include new build contemporary homes, basement excavation, substantial residential extensions, new swimming pools and remodelling projects.

Skilled in recognizing the potential for improvement, value and expansion of existing homes, be it by constructing an extension, house renovation or basement excavation. We have a proven track record in delivering award winning basement projects, interiors and architecture. View our Portfolio or contact us on 0207 7243040 to discuss your project.
