A(ttic)tecture transforms building 125, a former First Army Administration building, into a Center for Architecture. The former administration building employed typical spatial configuration of an office building where enclosed rooms are distributed on either side of a single-loaded corridor. Right across the building, a storagehouse, building 104 exists, creating a non-direct entry access to the building 125. This condition accompanied by the different programmatic phases of the project are weaved together through extending the building 125’s roof and its structural framework, encapsulating building 104 and creating diverse attic or ‘under-the-roof’ experiences for the building users. Contrary to building 125’s former functions, safeguarding information, A(ttic)tecture creates access to information and knowledge through varying degrees of visibility as well as remnants of architectural past of the building 125 and 104.
