District 56 Tallwood 1 in Langford, BC, Canada
Tallwood 1 is celebrated as the first tall mass timber building on Vancouver Island, the first Encapsulated Mass Timber Construction (EMTC) building constructed that meets the BC Building Code, and is the second tallest wood building in all of Canada.
This 12-storey residential building consists of 11 storeys of residential units on a 1-storey concrete podium commercial space and a 2-level concrete underground parkade. The top level is comprised of three unique penthouses, featuring vaulted mass timber ceilings with exposed CLT, providing a sense of luxury homes floating in the sky. The mass timber structure is a streamlined and efficient point-supported CLT floor plate on glulam columns, allowing easy integration with MEP services. The building is located in Langford, BC, one of Canada’s highest seismic regions. As such, the lateral system chosen is highly ductile eccentrically-braced steel frames, which achieve greater construction speeds than conventional reinforced concrete shear walls, with a significantly reduced embodied carbon content.
