The Abbey Residential Condominium at 384 Sunnyside Avenue is a conversion of Howard Park Methodist Church. Modern foundation stones on the building indicate that the Sunday School was built first in 1910, followed in 1914 by the church. The building is constructed in the Gothic Revival Style, combining robust masonry expression with fine window tracery. Heavy buttresses on the tower and transepts and crenellated parapets enhance this impression.

The church is protected by a Heritage Easement Agreement and is also designated under Part IV of the Ontario Heritage Act by the City of Toronto. The work involved the conservation of the exterior of the existing church building and administrative wing, and the conversion to 24 residential condominium apartments with the removal of most of the interior structure. ERA Architects was initially retained as the Heritage Architectural Consultant and prepared a Heritage Impact Statement and Conservation Plan on behalf of the owner, Taffycroft Enterprises. Later in the project, ERA became the Architect-of-Record.
