Our brief was to create a modern family kitchen and dining space with echoes of the industrial aesthetic of the client’s favourite local restaurant. In doing so, we considered the outside and inside as one: the steel and timber-framed extension was limited to filling in the side return, and identical finishes were used outside and inside. Triple glazing completed the transformation of a draughty back room into a warm, light, family hub. On the first floor we replanned a small dressing room as a family bathroom, allowing the existing bathroom to become a nursery. We also excavated a basement out of the existing cellar. Here we added a small shower room and WC so the playroom could double as a guest suite. The basement rooms also function as a cinema room. Fluted timber paneling conceals full-height storage and discreet sliding doors for additional privacy.
