BC Architects, in collaboration with ABBA architects and Adey Tadesse, won the competition for the Addis Abeba Chamber of Commerce Headquarters in Ethiopia with their approach towards a "glocaldesign". With the goal of sensibly involving local materials in this mid-high-rise building, this resulted in a local nature stone façade system inspired by a 'Netela' (threaded Ethiopian textile which so nicely shows the threads of cotton and which has a character of both shadow and transparency). More images and architects' description after the break.
