Construction continues at 12-24 Leith Hill Road, where Starlight Investments is building new rental apartments in an established Tower in the Park community northwest of the intersection of Don Mills Road and Sheppard Avenue East in North York. Designed by Architecture Unfolded, the infill project includes a 9-story mid-rise building and a series of three-story stacked townhouse blocks arranged around the existing apartment tower on the site west of Don Mills Train Station and Fairview Mall.
Construction began in February 2025. Until August 2025, activities were focused on underground work for the single underground level of the project. Temporary fences and safety barriers line the perimeter of the excavation pit, with an access opening where a yellow and black crawler excavator is stationed at the edge of the excavation pit. The crane, erected deeper into the site, reaches overhead and lifts a bucket of concrete over a concrete mixer parked near the 16-story apartment building.

Along the west side of the property we see one of the stacked townhouse blocks in early December 2025. The three-storey structure features sections of light and dark gray cladding fitted to the upper and lower sections respectively, with window openings fitted with black framed glazing. The western facade remains covered with a protective white tarp. Excavators are positioned on either side of the building, while the bare earth in the foreground marks the footprint on which another block of stacked townhouses will rise.

Later that month, the medium-sized rental building reached four floors, and formwork for the fifth floor was underway. A grid of red support posts supports the still-hardening floor tiles underneath. Perimeter safety railings and temporary fencing line the edges of the upper levels. The structure of the building includes a setback above the first floor along the west side. In the foreground, building materials and packaged palletized supplies are scattered around the site, along with equipment including a green rotary telehandler.

From a distance, in February 2026, the mid-rise has continued its rise. A construction elevator was installed along the south facade. On the top level under construction, formwork panels and decking are concentrated at the northern end of the floor slab, while a worker stands at the southern edge. Below, a white tarp wraps parts of the recently formed ground.

Now visible this month are the three townhouse blocks running south to north. The external walls of the southernmost block in the foreground are clad in timber panels and lined with blue weatherproof barrier strips prior to the installation of insulation and cladding. Projecting wooden balcony panels extend from the facades. Temporary guardrails line the edges of the roof. Construction fences and hoardings line the property line, while further north a green telehandler works on the completed blocks.

The middle building has now risen to seven floors, with formwork and decking for the eighth floor installed at the extreme north end. Above the fourth floor, where parapet walls run along the south and east facades, a setback in the massing can be seen. Along the east facade on the right we see protruding concrete balcony slabs.

Once the project is completed, 160 purpose-built rental apartments will be created with a height of 10.25 m and 37.83 m.
