David Rubenstein Treehouse at Harvard University

Construction required precise coordination to deliver Harvard’s first mass timber building within an active district undergoing simultaneous development. The exposed timber structure, including signature canted branching columns and cantilevered upper levels, demanded intensive preconstruction planning, advanced digital modeling and close collaboration among design, fabrication and construction teams. Extensive mockups, BIM coordination and constructability reviews helped resolve complex interfaces between the mass timber frame, low-carbon concrete systems, bird-safe glazing and high-performance façade assemblies. The project also incorporated the first structural application of recycled ground glass pozzolan concrete in Massachusetts, supporting Harvard’s ambitious sustainability goals while maintaining quality, schedule and long-term performance requirements.
