A 19,000-square-foot headquarters for the design and construction trades, built from the things its members build with. Forty- and twenty-foot shipping containers, stacked and paired, set the footprint and do four jobs at once: secure tenant storage reached from the parking lot, structure for the second floor, entry portals, and a conference room facing the Front Range. Every dimension in the building derives from them. A pre-engineered metal shell wraps the base, its ribbon windows reading as a light envelope over a heavy frame. Inside, polycarbonate fastens directly to the office studs so perimeter daylight filters through to the bullpen at the center, OSB makes the demising walls, and orange extension cord — the most disposable object on any job site — is remade as pendant fixtures over the shared table.
