In July 2017, the Brock Com­mons Tall­wood House opened, of­fer­ing ac­com­mo­da­tion for more than 400 stu­dents at The Univer­sity of Bri­tish Columbia in Canada. With its 18 storeys and 53 me­tres, Tall­wood House is the world’s high­est build­ing that is mainly con­structed of solid wood. The floors, for ex­am­ple, are made of cross-lam­i­nated wood sup­ported by pil­lars of lam­i­nated wood, while the cladding con­tains 70 % wood fi­bre. The foun­da­tion, lift shafts and stair­wells are made from con­crete, though.

The ad­van­tage of us­ing wood is, for ex­am­ple, that cross-lam­i­nated wood is al­most five times lighter than con­crete. Also, the con­trac­tor es­ti­mates that the con­struc­tion of the high-rise build­ing has led to the emis­sion of 2,432 tons of CO less than a sim­i­lar house made from con­crete.
