An independent steel structure has been inserted on top of the existing brick factory building to create several double-height (7 metres) studio spaces; architecture: Haworth Tompkins Architects, photo: Philip Vile Malcolm Fraser Architects performed a similar trick when they adapted three derelict mews buildings and a Victorian lawyers office in Edinburgh into light and spacious open-plan offices by adding a series of new metal roofs. These provide improved light and ventilation.
The two storeys that Project Orange have added to the roof of a redundant brick warehouse in Sheffield look like another building stacked on top. The upward extension replaces a pitched roof, creating three duplex studio offices within a powder-coated steel volume that both overlaps and bites through the original brick structure. A new restaurant and bar occupies the double-height warehouse space below, where it benefits from light through the original two-storey-high arched windows.
