The Glen Park neighbourhood in central Toronto offers a variety of housing options well-serviced by multiple means of transit. One of several proposed developments for the area is a new one at 280 Viewmount Ave, located a block from Glencairn subway station. Altree Developments has submitted a Zoning By-law Amendment application for a new mixed-use building at the site.

At the northeast corner of Viewmount Avenue and Marlee Avenue, the site is an assembly of two properties municipally known as 278 and 280 Viewmount Avenue. The former is home to a single-storey detached dwelling, while the latter a mixed-use building standing two storeys. The site is approximately 1,590m² in area.

The design includes indoor amenity spaces on floors two, five, and seven, with outdoor amenities on the fifth and seventh levels, for a total of 1,368m² evenly divided between indoor and outdoor space. The proposed building design includes step-backs at the top of the fourth and sixth floors, with the tower pushed towards the intersection. A green roof would be found at the top of the building.

Vehicles entering from Viewmount Avenue would have four levels of underground parking with 85 parking spaces, along with 387 bicycle parking spots at grade. Bicyclists have a bike lane running along Marlee Avenue. Those commuting by car are well-serviced by close access to the Allen Expressway and Highway 401.

Standing 113m with 33 storeys and 342 residential units, the proposed design by Graziani + Corazza Architects would transform the site in what the proponents describe as in line with future developments planned for the area. The proposal calls for a podium of four storeys with about 296m² of ground floor retail space that customers would enter via Marlee Avenue. Residents would find the entrance and lobby at the southwest corner of the site off of Marlee Avenue.
