House extension, London

House extension, London

The clients wanted a new play room and bedroom for their listed Georgian terraced house in Marylebone, central London. The challenge for Halvorsen Architects was to provide reasonable accommodation on a very narrow site with onerous planning constraints.

The scheme was for a two-storey rear extension divided into three bays. Each bay has a timber frame, but the frames are filled with different materials: brick or glass, according to orientation, privacy and planning requirements. There are views from the kitchen through the exceptionally light play room to the garden. A new access to the garden has been created from the main living areas via a lightweight steel stair from the new first floor terrace.
