Mid-rise Construction

Worldwide, there’s a trend toward the construction of taller wood buildings, from the Stadthaus in the UK, which includes eight stories of cross laminated timber (CLT) over one story of concrete, to the four- and five-story wood buildings now common throughout the US.

It’s being driven to a large degree by cost. While material prices fluctuate, wood almost always costs less. Plus, wood construction is fast and wood’s relative light weight reduces demand on the foundation design.

At the same time, wood offers other benefits. Wood buildings are safe. Building codes require all building systems to perform to the same level of safety, regardless of material used, and wood meets code for a range of mid-rise building types. Wood-frame buildings are also lighter and have more repetition and ductility than other structures, which means they perform well during earthquakes and high wind events. Wood buildings are versatile and adaptable. Innovative technologies continue to expand the possibilities for taller walls, longer spans and higher wood buildings. And wood is inherently green. It’s renewable and sustainable, contributes to a building’s energy efficiency, and can be used as a low-carbon alternative to steel, concrete and masonry in many mid-rise applications.
