Timber · Clapham (SW4, SW11)

Timber windows in Clapham

Timber windows preserve the proportion and detail of traditional London homes while improving comfort, security, and glazing performance.

Clapham timber window work usually splits two ways: a planning-sensitive front elevation to Old Town, Abbeville Village or the Common, and a more flexible rear that has already been opened up for an extension. We replace front-facing sashes in painted softwood or engineered timber with matched horns, slim glazing bars and putty-finish beads, then handle the side return and rear with timber casements that sit cleanly against new brick or render. The result reads as period from the street and as a refurbished family home from the garden — which is the brief most SW4 and SW11 owners are working to once a side return is in.

Conservation areas around Clapham Common and Old Town shape the front elevation; rear extensions usually have more freedom on materials and frame style.
