Alterations to a Property Designated Under Part V of the Ontario Heritage Act - 1067 Yonge Street

The proposal involves the demolition of an existing three-storey rear addition that was constructed in the early 1950s, a two-storey wing to the south-east of the house-form building (date of construction unknown) and a small part of the rear of the original house. A new four-storey rear addition is proposed which would be set behind the existing hipped roof of the heritage building. A new one-storey side addition is also proposed which would provide access to the below grade parking garage. The additions although large and contemporary in design are considered appropriate from a heritage point of view given the context of this property along Yonge Street. As part of the scheme a comprehensive conservation strategy for the heritage building is proposed. This would involve replacing the existing (altered) roof with one that matches the original and includes the use of slate, the reinstatement of the original flared edge to the roof and new chimneys to match the originals. In addition the modern windows and doors would be replaced by with new wood units that would be designed to match the originals. The existing office use of the property would continue. Heritage Planning has worked with the applicant to ensure that the proposed alterations meet the general intent of the South Rosedale HCD Study's guidelines and would not have a negative impact on the existing heritage building and existing context within the South Rosedale HCD. The applicant still needs approval under the Planning Act (minor variance and site plan approval) and therefore this application relates solely to the approval that is required under the provisions of the Ontario Heritage Act.
