Central Exchange reinvents a pair of robust but derelict historic buildings in Oklahoma City—originally warehouse and garage for the Pioneer Telephone Company—into flexible space for restaurants, brewery, retail and office. To exploit their intrinsic character, the buildings are stripped back to their concrete frame and structural brick shells. On the warehouse building lightwells are cut into the floor slab, which, combined with large perimeter windows draw natural light deep into all four tenant floors. A new addition on the north denotes entrance while the expressed stairs connect the floors and stimulate chance interactions. A modern canopy extends from a new north addition providing cover while physically connecting the historically separated buildings. The new layout accommodates a pinwheel of activity arranged around a central promenade acting as both circulation and social core.
