The Brock Commons residence hall at the University of British Columbia has become the latest world’s tallest wood-framed building.  The 18-story, $39 million tower is a hybrid mass timber structure designed by Acton Ostry Architects.  More than 400 students will move in when the tower is completed in September 2017.


Wood construction started on June 6, 2016 and progressed at a rate of two floors per week. The structure incorporates 1,302 glulam columns and 464 5-ply CLT panels each 169 mm thick throughout the 16 floors of wood construction.  It is wrapped in a panelized envelope system.
It takes about six minutes for U.S. and Canadian forests to grow the 2,233 cubic meters of wood that was used in this project.  The estimated avoided and sequestered greenhouse gases from the wood used in the building is 2,432 metric tonnes of CO₂, equivalent to removing 511 cars off the road for a year.
