80 Atlantic is the first mass timber wood-framed commercial building to be constructed in Toronto in over a century.

The building rises five storeys plus a mechanical penthouse and has a total area of approximately 95,000 sq. ft. It is comprised of cast-in-place concrete up to the second floor, with the building’s top four floors constructed of Nail-Laminated Timber (NLT) floor deck supported on glulam columns and beams.

Exposed mass timber structural elements throughout the upper floors of the building to showcase wood elements.

RJC Engineers worked with the mass timber supplier to economize column sizes to enable the client’s vision of embedded conduits via covered chases to hide services.

The facility includes retail, support space, and lobby space at ground floor, with two levels of underground parking.

The final product is a heavy timber construction for office use, with a building layout that is visually appealing, while remaining cost-effective.
