Trace Lofts is the redevelopment of the nearly-abandoned Trace manufacturing building. The project required a careful analysis of the structural capacity and an efficient reconfiguration of this unusual triangular masonry and wood-frame structure. Using a unique contemporary heavy timber structural system, and working with the triangular building form, we were able to add two full floors and create forty four condominium residences, many with lofts and private terraces without substantially modifying the foundations or vertical structure. Additional efficiencies were created by linking the parking access with the new Trace North building. The existing ground floor retail façade was carefully modified to provide universal accessibility and a new street presence.
