Two new rooftop houses for the Piper Building in Fulham, London.

These rooftop houses were converted out of two tank rooms on the roof of a former British Gas laboratory, altered in the mid-1990s into luxury flats. A modular, steel-framed construction system was used, allowing the units to be assembled and fully fitted out internally in the factory, transported by truck to London and installed by crane in a few days. The two ends of each unit are fully glazed, framing panoramic views over the Thames River, while the remaining facades are solid with smaller windows and clad in metal mesh, which catches and shimmers in the light.
