British Columbia has doubled height limits allowed for timber towers and countries around the world are following suit
British Columbia is no stranger to wooden giants. Along its western coast, Douglas fir and Sitka spruce trees topping 60 meters in height have in some cases weathered nearly a millennium of storms.
Now a growing chorus of architects, foresters and engineers want the provinces biggest city to grow another cluster of wooden giants: timber skyscrapers.
Already, Vancouvers 18-storey Brock Commons tower stands as a testament to the vast possibilities of wood. Once the worlds tallest timber building, it was built cheaper, faster and with less environmental impact than a comparable steel and concrete structure would have been offsetting an estimated 2,432 metric tonnes of carbon.
Now the provincial government has changed its building codes, effectively doubling the height limit for wood-frame buildings to 12 storeys (Brock Commons was granted an exception when it was built). The Canadian government is expected to match BCs codes nationwide.
