Project One

Project One, a four-story, 17,000-sf mixed-use residential building in Oakland, California, is one of the first projects in the US to utilize cross-laminated timber (CLT) made from structural composite lumber (SCL). Built on a zero-lot-line site, this 'proof-of-concept' pilot project was undertaken as a means to rethink traditional components, assemblies, and construction methods in an effort to maximize the promise and potential of off-site fabrication. With a primary structure erection time of just 23 working days, and an overall construction schedule of 10 months compared to 14 months using traditional methods, it achieved just that. Each floor plate consists of 19 mass timber panels erected in approximately three hours. The team further compressed the schedule by using prefabricated wall panels and coordinating MEP holes and penetrations in a 3D building model, minimizing on-site work. The result is a project that delivers nine market rate apartments, ground floor retail, and a parking garage, as well as a building system that has the potential to change how future urban mixed-use construction is realized.
