Architecture-loving visitors to Western Canada’s biggest city have alofty new landmark to crane their cameras at, following the opening of the world’s tallest contemporary wooden building. Located on Vancouver’s tree-lined University of British Columbia (UBC) campus, the sleek, 53-metre-high Brock Commons Tallwood House student residence welcomed its first intake of 404 upper-level and graduate occupants this fall. …Regions around the world are jostling to dominate the fast-growing wooden construction sector, a sustainable building alternative that stores rather than emits carbon dioxide. …But while UBC has several other handsome contemporary wooden buildings worth visiting, it’s innovative new Tallwood House tower won’t be a world record holder for much longer.  Already under construction in Vienna, the 24-storey timber hybrid HoHo Tower, will have risen to an eye-popping 84 meters by the time it’s completed sometime in 2018.
