BACKGROUND The house at 255 MacKay Street (circa 1895) is a two-storey building with an L-shaped plan and a medium pitched, hipped roof. The building features returned eaves, brick hood mouldings, gabled dormer windows, and porch with decorative millwork. The 4 house was constructed as the manse for MacKay United Church, located next door, and is situated across the street from Rideau Hall (see Documents 1 and 2). Christina MacKay, daughter of Thomas MacKay, financed the construction of the manse and gifted it to the church. This block of MacKay Street is typified by one-and-a-half storey front gabled houses. The New Edinburgh Heritage Conservation District (HCD) was designated in 2001 and its heritage conservation plan, written according to the requirements of the post-2005 Ontario Heritage Act, was approved in 2016. The New Edinburgh Heritage Conservation District is a significant example of a small 19th century village located within Ottawa. It is significant for its historical associations, architectural and contextual values. Laid out by Thomas MacKay, who lived at Rideau Hall and had established an industrial complex of mills at Rideau Falls, the village was settled by many of MacKay’s workers. Incorporated in 1867, and annexed by the City of Ottawa in 1887, New Edinburgh was a self-sufficient community well into the 20th century. Primarily residential in character, the heritage conservation district features a wide range of building types in a variety of styles and types built in the 19th and 20th centuries. This report has been prepared because the alteration to a property in a heritage conservation district designated under Part V of the Ontario Heritage Act requires the approval of City Council. The house at 255 MacKay is categorized as a ‘contributing building’ within the New Edinburgh Heritage Conservation District. DISCUSSION The house at 255 MacKay Street (see Documents 4 and 5) is a late Queen Anne Revival style house built by local contractor Henry Avery. Since 2014, the building has been occupied by the New Edinburgh Community and Arts Centre, and is currently listed for sale. The applicant proposes to purchase the house and convert it into a semi-detached residence through an addition to the northwest façade of the building. The applicant has also applied for a Zoning By-Law amendment for the property from I1A, Minor Institutional Subzone A, to R4S, Residential Fourth Density Subzone S. Recommendation 1 The intent of the project is to create a semi-detached house by constructing a new addition to the northwest, while retaining as much as possible of the original structure. The proposed alterations include an addition to the northwest, a small addition to the southeast and the demolition of an existing rear addition constructed in the 1960s. Other elements of the proposal include a new porch, the creation of new window 5 openings on the second floor and on the southeast façade, as well as the removal of gabled dormers to be replaced with shed dormers. The new addition will create a nearly symmetrical façade, with the new portion being contemporary in its use of materials. It will have a projecting hipped bay and feature stucco and grey cement panels. The new windows will match the windows on the existing house in terms of proportion and placement. A second smaller addition will be added to the southeast façade. In order to accommodate the addition, the existing truncated hipped roof will be extended to the northwest, new shed dormers will be added on either side, and the existing front gabled dormer window will be replaced by a larger central shed dormer. To balance the façade, a window will be added to the second floor, above the existing entrance. The new window will match the existing in terms of size, however will not have the same brick hood mouldings that are present on the other windows. This absence of brick detailing will make it distinguishable from the other windows to indicate that the window was not an original feature of the house. The existing rear addition will be removed in order to build the new addition. This 1960s addition has no heritage value. The contemporary additions will be distinguishable and subordinate from the original house in that they will be clad in modern materials and no higher than the original house. The original form and many of the heritage attributes of the manse will remain visible and prominent on the site. The addition will be compatible in that it will echo the same features as the manse, and not detract from the historic building. Section 8.5.2 of the New Edinburgh HCD Plan has guidelines about Conservation and Maintenance. It states that the removal of historic porches will not be permitted. A circa 1900 photograph (Document 4) shows the manse with a decorative wood porch. In recent years, some alterations were made in order to make it accessible. A handicapped ramp and new railing were added, and the porch floor was raised however, the roof components with its decorative millwork remain original. The porch remains one of the distinguishing features of the building. The proposal includes a reconstructed porch to replicate the original features, and will include the addition of a modern pediment over the southeast door to echo the original pediment. The modern pediment will be located on the portion of the porch adjoining the historic side of the house, while the historic pediment will be on the contemporary half. Creating the new pediment with glass and a simplified design will make it distinguishable from the original porch, and reinforce the asymmetrical design of the original manse.
