While Ontario has only just approved wood as a material for mid-rise structures up to six storeys, Vancouver architect Michael Green is at the forefront of a push to design and build highrise towers using cross laminated timber (CLT) also known as mass timber.
Green and his team at Michael Green Architecture have already completed the eight-storey Wood Innovation Design Centre (WIDC) in Prince George, B.C. at the University of Northern British Columbia, winning the Royal Architectural Institute of Canada (RAIC) Innovation in Architecture award for 2015. At 29.5 metres, it is North America’s tallest timber building.
Other wood structures are also rising around the world where 10-storeys has been the apex but Green says that will soon be eclipsed. He should know, he literally co-wrote the book on wood towers in 2012, The Case for Tall Wood Building, How Mass Timber Offers a Safe, Economical, and Environmentally Friendly Alternative for Tall Building Structures and has designed a 30-storey wood structure to demonstrate feasibility.
