Our clients asked us to extend the existing basement of their 1940s semi-detached house in St John’s Wood. We extended towards the front garden, creating space for a new gym, spa, and a ‘granny flat’ to serve as a guest suite for visiting family and friends.

The new floor plan includes a living/dining room, a concealed kitchen, and a bedroom with an en-suite shower room. Natural light and ventilation enhance all living spaces through well-placed skylights, light wells, and an air recovery system.

The flat is accessible both from the house and directly from the street via the main light well. Cleverly designed staggered planting creates a beautiful focal point for the new extension. Additionally, the extra space includes a new spa area, attached to the fully refurbished gymnasium, which now features an endless pool and sauna.

We carefully selected materials for both the exterior and interior of the house. The use of various shades, colours, and textures from natural and man-made materials was inspired by nature.
