MIT workshop develops sustainable, mass timber prototype modelled after longhouse structures

a workshop at the massachusetts institute of technology (MIT) has developed a mass timber design building prototype modelled after the longhouse, a traditional building type that has been historically used as a place for community gatherings. the prototype studies how mass timber products can be used to create modern buildings, demonstrating its value against conventional materials such as concrete.

the MIT longhouse prototype comprises of a series of timber laminated veneer lumber (LVL) arches spanning across the building’s shorter dimension. each arch utilizes a thin-walled triangular profile to minimize deformations in the structure and provide overall rigidity to the building. the structure would serve as a multifunctional building that could accommodate a variety of events, from co-working, exercise classes, social mixers, exhibitions, dinner gatherings and lectures.

the building design integrates sustainable features to become an energy producer. its orientation and the depth and angle of the sawtooth roof can be tuned for local solar conditions and natural daylighting needs. a low window to wall ratio with a highly insulated envelope allows for an energy efficient building. 

led by research scientist john klein, the cross-disciplinary team at the mass timber design workshop have developed research that shows how mass timber structures have a lower carbon footprint and can be engineered for substantial strength and fire resistance. mass timber buildings are becoming more common throughout north america, most notably due to the technology’s environmental benefits and the potential impacts it can have on america’s forest health and restoration.
