The 42-storey tower located on Yonge Street in downtown Toronto will be a residential condominium constructed on top of a mixed-use podium and incorporate heritage elements, including the existing historic clock tower dating back to 1870. The entire property is owned by Kingsett Capital.
Located on Yonge Street, the world’s longest street and Toronto’s central transportation avenue, the new 42-storey residential tower will be on a site bounded by Grovesnor Street to the north and Grenville Street to the south. The tower will dominate a currently low to mid-rise neighborhood, revitalizing its streetscape, and providing its residents with striking views of the area and proximity to amenities, transit and the downtown core. The project is intended primarily for residential use but its podium houses both amenities for the residents and the retail/commercial spaces one expects in a modern, mixed-use development downtown. Set-backs in the podium provide multiple terraces for both residential amenities and commercial/restaurant spaces. Four levels of below grade parking will also provide extensive storage for bicycles. Existing heritage elements, notably the historic clock tower, are retained and integrated into the development.
Challenge: Integrate different grids for the residential tower, retail/commercial spaces, and the parking levels.
Solution: We concentrated the structural elements for the tower’s lateral system on the west side of the tower combined with a slightly offset core. In this position, they could continue down with relatively little modification. The use of two corridor walls as shear walls in lieu of corresponding demising walls on the east side of the tower allowed the use of a column grid on that side of the tower that was consistent with both the and amenity level layouts. Transfers were required to support relatively small column offsets and the lateral capacity of the tower was unchanged.
