We Are Your Local Architectural Practice for Extensions and Loft Conversions in West and South-West London
Just Extend Your House is a residential architectural practice specialising in house extensions, loft conversions, and refurbishments across Richmond, Ealing, Hounslow, Wandsworth, Merton, and Elmbridge. Established in 2011, we have completed more than 660 residential projects ranging from modest extensions to full home refurbishments.
Our practice is led by one principal designer and supported by experienced structural engineers, party wall surveyors, and specialist consultants. This allows us to provide personal, attentive service while maintaining strong technical capability.
