KJC Architects is a RIBA Chartered Practice based in Carshalton, Surrey, specialising in design-led residential architecture. Founded by Kevin Clarke, we work with homeowners across Sutton, Kingswood, Cobham, Esher, Wimbledon, Banstead and the wider Surrey and South London area.
We are known for extensions, loft conversions and whole-house refurbishments that are built, not just designed. Unlike many practices, we stay involved through construction — managing the project from first sketch to final handover. This hands-on approach means fewer surprises, better build quality, and a home that matches the drawings.
Our clients range from families extending Victorian and Edwardian homes in conservation areas to homeowners commissioning contemporary new-build designs on larger plots. What unites them is a desire for architecture that is thoughtful, practical and beautifully finished.
With over a decade of experience navigating planning across Sutton, Croydon, Reigate & Banstead, Elmbridge and Merton councils, we understand the local planning landscape and how to get the best outcome for your property.
