Trolleybus Proposes 15 Storeys on Cosburn east of Broadview

A redevelopment is proposed in the Broadview North neighbourhood in the East York area of Toronto on an assembly of properties from 5 through 19 Cosburn Avenue and 8 through 40 Gowan Avenue. Trolleybus Urban Development Inc is seeking a Zoning By-Law Amendment for a 15-storey, 52.5 metre-tall condominium tower that steps down to 8 storeys facing Gowan Avenue. Designed by IBI Group, the proposal includes a new public park and mid-block connection.

The site is a consolidation of 8 detached single family dwellings and 4 semi-detached buildings, 16 units in total, which are set for demolishment in this proposal. Adjacent properties to the west and south consist of low-rise detached and semi-detached dwellings. Across the street to the north are low-rise houses and apartment buildings. Adjacent to the east is a 22-storey Tower-in-the-Park style apartment tower. The proposal would to add to the growing history of lot consolidation and apartment redevelopment in the area which has been reignited recently largely due to a proposed Ontario Line station to be built at Cosburn and Pape.

The proposed 15-storey building would face Cosburn Ave with its uppermost floors stepping down towards the south. An 8-storey podium building facing Gowan Avenue would begin to step back above the fourth floor, transitioning to the lower-scale neighbourhood to the south. The Gowan building would feature a 450 m² landscaped amenity terrace atop it, adjacent to a 65 m² indoor amenity space on the ninth floor of the tower to the north. A 120 m² green roof would top the southeast corner of the Gowan building. A new pedestrian connection is proposed to be established along the western property line, extending north from Gowan Avenue to a proposed 456 m² public park in the northwest corner of the site facing Cosburn.
