Architects in West Sussex

Founded more than 30 years ago, Gregory Phillips Architects is a multi-award winning architecture studio specialising in contemporary residential design. 

Established as one of the UK’s leading residential architects, we deliver the finest homes to the highest architectural quality with a carefully considered approach. 

Whether the project is an extension, a renovation or an entirely new house design, every project we work on is transformative and we care about every detail. 

We strive for every project to be our best yet.

Gregory Philips Architects have carried out a number projects throughout West Sussex, primarily in renovation.

We provide a unique, considered and professional approach to high quality residential design.

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, and new swimming pools.

Recently we worked on a listed house and stables in Chilgrove. In this project we worked hard to maintain beautiful original features, such as the stable screen doors and brick flooring. Inside we created new contemporary interiors for a unique and comfortable living space.

Our team of talented architects and interior designers is dedicated to crafting distinctive and functional spaces that consistently surpass our clients’ expectations. Whether you’re contemplating a new-build home, an extension to a Listed property, or remodelling project, we possess the planning skills and experience to bring your vision to life.
