Arena Stage involved the upgrade of two heritage theatres, the addition of a new experimental theatre and support spaces under a new roof and timber façade - a catalyst for the redevelopment of a derelict Washington, DC neighbourhood one mile south of the National Mall. Arena Stage's 500-foot-long roof is supported on a new concrete ‘Cradle’ theater and a 650-foot-long glazed timber façade, forming an acoustic barrier around the freestanding heritage theatres. This was, in every respect, a complex structure to build. The general contractor and entire team of consultants were fully engaged with the project, paying close attention to detail in planning, 3D-modeling, and the preparation of shop drawings. To ensure smooth execution of the timber façade, Fast + Epp's related design-build company, StructureCraft Builders Inc., took on the contract for its design, testing, fabrication and installation. Arena Stage involves the unprecedented use of architecturally-exposed engineered wood, by far the most sustainable structural material. The custom timber façade is not only structurally unique, but also uniquely serves as acoustical barrier and roof support, and costs less than commercially-available alternatives.
