The Corporation of London, with engineer Whitby Bird & Partners, has designed a linear extension to the cafeteria in Golders Hill Park, North West London.
The existing building, a lightweight timber-framed single-storey structure with paved terrace, was originally designed as a tea room and had become overcrowded and in need of modernisation. The 165m2 extension is raised on a brick plinth in order to take advantage of the existing terrace, and provides a single-storey space with an average internal height of 2.5m.
The new building had to be economical and of a sufficiently simple construction to be built during the winter break. A stainless-steel roof, lined with birch-faced ply, is supported on a simple steel portal frame. The steel frame is used in combination with lightweight pre-fabricated panels which are predominantly glazed to take full advantage of extensive views over the park. The frame was constructed using back-to-back steel angles which facilitated the insertion of pre-fabricated timber window units. High- level opening windows and a continuous brise soleil combine to overcome solar glare. The tender price for the project was £143,000.
