Oak House is a new family home on a challenging, secluded site in Highgate, near Hampstead Heath. Carefully conceived to respond to its setting, the first floor is clad in vertical green oak appearing to hover above a Portland stone base and referencing the canopy of the surrounding trees. Planning constraints limited height, so a basement accommodates a home office and utilities within the 320m² scheme. Living spaces maximise garden views and daylight, with flexible open-plan arrangements. Oak features throughout the interiors, including joinery and a folding stair. Rooflights bring natural light deep into the plan, while moveable oak shutters on the first floor provide shading. The basement office has independent access via a glazed lightwell and external stair.
