House Extension & Kitchen
📍 Harrow on the Hill, HA1
Victorian Semi-Detached 6m Rear Extension & Kitchen
The client required the demolition of a dated 1970s conservatory and the construction of a contemporary flat-roof extension with a 3m x 1.5m flush glass roof lantern. We installed a three-piece steel goalpost arrangement to knock through the original rear exterior wall, creating a seamless 42m² open-plan kitchen-living space with polished concrete flooring and bespoke German handleless cabinetry.
