BACKGROUND: The Development and Technical Services Department is in receipt of Heritage Permit Application HPA-2010-IV-019. The applicant is seeking Council’s permission to install two new carriage doors on the north elevation of the drive shed and two roof vents on the west elevation of the drive shed located at the property municipally addressed 300 Joseph Schoerg Crescent. î ó ï REPORT: The subject property is located on the south side of Joseph Schoerg Crescent in the Pioneer Tower West community, and is subject to a Heritage Conservation Easement Agreement and designation under Part IV of the Ontario Heritage Act. The key features that define the heritage character of this property include: the Betzner Farmhouse Building; the Betzner Drive Shed Building; and, the Cultural Heritage Landscape. The heritage features identified in the easement agreement are the same as those referenced in the designating by-law. The Part IV Designating By-law describes the Betzner Drive Shed Building “As a typical utilitarian accessory structure that added to the efficiency of living and working on the former farmstead, and also having historic ties to the Pioneer founding families. Specific architectural features and details of significance include all exterior building elevations, the fieldstone foundation, roof and roofline, window and door openings, door hardware on north and west elevations, and all 6/6 windows.” The applicant is requesting permission to install two new carriage doors on the north elevation of the drive shed and two roof vents on the west elevation of the drive shed. Proposed New Carriage Doors on Drive Shed The applicant has proposed two options for the new carriage doors on the north elevation of the drive shed. The first option involves: installing two new 9 feet by 7 feet side hinged cedar carriage doors with a “Z” brace design; installing two new 9 feet by 3 feet cedar fixed panels; installing a new wooden shield to match the existing; and, relocating the existing rollers so that they will be centred on the fixed panels. The carriage doors will swing outward. The applicant has indicated that when closed, the carriage doors and fixed panels will resemble a functioning sliding door and together the carriage doors and fixed panels will be the same height as the existing sliding doors. The balance of the north elevation will be re-clad with board and batten in accordance with plans approved in a previous Heritage Permit Application. Heritage Planning staff note that this option will result in a visual alteration to the north elevation but the alteration will be distinguishable as a new element not an original element on the north elevation. Also, recognizing that the repair or full replacement of board and batten cladding is a normal maintenance practice the alteration could be reversed. Although the interior of the drive shed is not designated, it is important to note that the installation of two new carriage doors will facilitate the adaptive re-use as a garage for parking cars. In order to tolerate the weight of two cars, a portion of the under croft of the drive shed will be filled with engineered fill and capped with a concrete pad with vertical steel rebar. Compaction of the fill may place stress on the existing fieldstone foundation. As a result, Heritage Planning staff recommend that the Heritage Permit Application be conditional upon the submission of detailed drawings stamped by a professional engineer. î ó î The second option involves: installing two new 9 feet by 10 feet hinged pine tongue and groove carriage doors; relocating the existing rollers so they will be centred on the carriage doors; and, cutting the original roller hardware. The carriage doors will swing outwards. The applicant has indicated that when closed, the carriage doors will resemble the existing functioning slide door. The balance of the north elevation will be re-clad with board and batten in accordance with plans approved in a previous Heritage Permit Application. Heritage Planning staff note that this option will result in irreversible damage to the north elevation door hardware, which is identified as a heritage attribute. This option also may not distinguish the carriage doors as a new element on the north elevation. As a result, Heritage Planning staff do not recommend approval of the second option. Proposed New Roof Vents on Drive Shed The two roof vents will be installed 8 feet from each gable end near the ridge of the roofline on the west elevation of the drive shed. The applicant is proposing to install the slant back roof vent by duraflo. Duraflo is able to manufacture roof vents in light colours such as grey or weatherwood. The applicant has suggested that the weatherwood colour would be an appropriate match. Heritage Planning staff believe that the weatherwood colour will blend well with the existing asphalt shingles and not detract from the character of the drive shed. It is noted that some members of Heritage Kitchener expressed concern with the introduction of modern roof vents. It was suggested that the applicant consider the installation of a ridge vent or a cupola. The applicant expressed concern with installing a ridge vent because it would be expensive especially given the fact that the roof, which was recently rebuilt, would have to be redone. The applicant also considered the installation of a cupola; however, Heritage Planning staff expressed concern. The introduction of a cupola is not appropriate because the drive shed is a Mennonite Georgian utilitarian structure and cupolas were not commonly associated with Georgian architecture. In addition, the introduction of a cupola introduces a decorative element that is not consistent with the typically modest Mennonite utilitarian design. In reviewing the merits of the application, City staff note the following: With respect to the two new carriage doors: The installation of two new carriage doors with facilitate the adaptive re-use of o the drive shed for the purpose of a garage for parking cars; The installation of fixed panels will prevent the need to cut and irreversibly o damage the roller hardware; The installation of a new wooden shield will match the existing; o When closed, the carriage doors and fixed panels will resemble a functioning o sliding door and together the carriage doors and fixed panels will be the same height as the existing sliding doors; The new carriage doors will be distinguishable as a new element; and, o The alterations could be reversed. o With respect to the two roof vents: The two roof vents will provide air circulation allowing warm air to escape from o the attic of the drive shed; The two roof vents will blend with the existing asphalt roof; and, o The final proposed colour, material and size will be reviewed and approved by o Heritage Planning staff in order to ensure that the two roof vents will not detract from the character and heritage attributes of the drive shed. î ó í FINANCIAL IMPLICATIONS: None CONCLUSION: The proposed hinged cedar carriage doors with “Z” brace design and fixed cedar panels as well as the proposed roof vents will not detract from the Part IV designation. Accordingly, staff recommends approval of HPA-2010-IV-019.
