Two years have passed since UrbanToronto's front page last turned its lens on 201 Sterling Road, where Marlin Spring DevelopmentsHouse of Assembly is growing skywards in Toronto’s Junction Triangle. A 10-minute walk southeast of Dundas West station, this 17-storey mixed-use building designed by Graziani + Corazza Architects has made steady progress. The project is part of the Sterling Master Plan, a broader initiative aiming to rejuvenate this west-end neighbourhood.

In July, 2023, a bit over a year after shoring rigs were spotted onsite, the excavation activity is finished, with lower level work surrounding a red and white tower crane that was installed in May, 2023. Shoring walls can be seen, reinforced rakers at the bottom of the site, while tiebacks secure the walls into the surrounding earth at mid-height.

By December, 2023 the structure was above grade, with the first storey completed and activities concentrated on forming the second floor. Behind concrete walls, formwork is positioned in preparation for the next for concrete pour, while above, the tower crane’s jib manoeuvres the concrete bucket to a construction crew.

Catching up to recent work, a view from the Dundas Street bridge over the Barrie GO line provides context for the development. We see the south elevation of the building and construction progress at the top, having reached the 14th floor. The eastern end of this floor has been formed, while to the left of the tower crane, walls have been formed. to the left, the restored Tower Automotive Building serves as a historic anchor for the area.

 This close-up showcases the cladding panels mid-installation. The panels are brick-faced, while masonry frames the window openings, currently lined with safety fencing.

Looking north, sandstone-coloured panels have been applied on the lower levels facing Sterling Road, some hidden behind a yellow mobile crane, while the framing rises in a stepped pattern at the east end of building. We see a central recessed section, with a step-back above the first two storeys, that features extensive glazing and projecting balconies. Brick panel cladding is installed for most of the facade except for the top few storeys, with glazing and black mullions visible on several storeys of the brick section on the west and east ends.

As construction continues, the House of Assembly will reach 17 storeys and a final height of 61.85m, and house 266 residential units.
