80 Atlantic Avenue

80 Atlantic Wood Frame Construction

Location: Toronto, Ontario, Canada
Developer: Hullmark
Architects: Quadrangle

80 Atlantic was the first commercial building in Toronto to be built using mass timber-frame construction in a generation. In 2015 Ontario amended the Ontario Building Code to allow new wood frame buildings to reach up to six storeys. Concrete was still used for the ground floor of the building and engineered timber frame for the top four storeys. The exposed wood structure is comprised of glue-laminated (“glulam”) columns and beams with nail-laminated timber (NLT) panels. The elevator and stair cores remain reinforced concrete by integrating natural and high-performance materials. The 5-storey office building has 80,000 sq.ft. of office space and nearly 8000 sq.ft. of retail space. HGC provided comprehensive acoustical consulting services for this mass timber project, with the exception of tenant and retail space fit-outs.
