The cladding of the extension echoes the red clay roof tiles and the ornamental detailing of the house’s original front porch and window. Each tile shape is of a traditional profile, carefully crafted by Keymer Tiles, one of the oldest established roofing brands in the UK, crafting handmade tiles since 1588. There are a variety of shapes in the envelope, ranging from clubs and fish-scale profiles at the peak of the roof, overlapping onto angular arrowheads, and finally to a plain square cut at the base of the extension. Special bespoke edge and corner pieces along the roofer create a seamless textural shift across the surface.

Natural daylight is brought into the building with glazing on the south elevation, minimised to reduce solar gain and overheating. Internally, the design of the sunken living room was informed by the typology of historical Victorian boxing rings of the area, reimagined as an intimate space and conversational pit. It offers a unique transitioning threshold between the kitchen and the garden, a social and reflective space which can be used in all seasons.
