This will be the new HQ for the Corus Colorcoat division based in Shotton North Wales, where Colorcoat pre-finished steel products are manufactured. It will bring together 180 staff in an exemplar building designed to demonstrate how steel can inform leading edge sustainable design. The Construction Office will be a striking new landmark at the entrance to the Corus site. The strong circular form of the 3800sq.m four storey office will be highly visible in its location in front of the huge production sheds and adjacent to the freshwater cooling lagoons. The design makes the most of both the coating process and lagoons as innovative sources of energy: surplus steam and heat from the coatings plant will be harnessed to heat the new offices, and the lagoons will be used as a heat sink to cool the building. The central atrium will enable the building to be naturally ventilated. The external skin of the drum is expressed in finned, curved walls which incorporate Corus deep profile cladding. The curve is accentuated by sweeping screens of steel mesh which float in front of the main office elevations providing solar protection but allowing uninterrupted views out. Throughout the building inside and out Corus products are specified to highlight their quality, versatility and sustainability credentials.
