The original structure, at Golden Lane, London EC1, was built in the late 1920s as a showroom for clothing at ground floor, with clothing manufacture on upper floors. Floor-by-floor refurbishment over several years has included the now-white exterior. The top floor has been extended to provide a meeting space, open terrace and second egress.
The design principle was to encapsulate the volume and its frame within a glass skin standing free of structure and walls, allowing the roof pavilion to float above the building. Components had to be small enough to be transported to the top of the building for assembly - galvanised steel sections, butt-jointed, double-glazed units and a proprietary roof.
The engineer was Curtins Consulting Engineers; steelwork and roof by Faircloth; glazing by Alcono.
