Mass timber, a wood-based building design and construction technology, has received attention over the past few decades given its efficiency, speed, precision, and versatility in construction for low to high-rise applications. 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.

MIT Mass Timber Design, a design workshop at the Massachusetts Institute of Technology, has explored these technologies' design and engineering potential and developed a mass timber-building prototype: The Longhouse.
