A new triplex development built to Passive House green building standards could replace an existing semi-detached home at 644 Woodland Drive in Grandview-Woodland.
The proposal was submitted by Michael Lemon Architect and features three strata-titled townhomes fronting Woodland Drive with two parking spaces accessed from the lane. The family-sized homes would replace a 1950s era duplex situated on the corner of Woodland Drive and East Georgia Street, directly across from Woodland Park.
The proposed design of the homes centres on sustainability in its commitment to obtaining certification from the Passive House Institute in Darmstadt, Germany. Residents will benefit from consistent thermal comfort, low exterior sound transmission, and superior air quality through cantilevered architectural elements that create shade, additional insulation that goes beyond code, and operable skylights for natural ventilation and light.
“Meeting this standard will reduce the heating and cooling energy required by up to 90 percent,” reads the design rationale. “Low energy consumption benefits the future occupants by keeping operating costs down, but also contributes to a more livable city and sustainable planet by reducing the greenhouse gas emissions from energy use.”
The homes would showcase contemporary architectural design, highlighted by a series of peaked roofs inspired by those found on surrounding homes. The peaks on the two northern units are created by a gable outline that frames and is open to two rooftop decks. The open design not only allows for expansive private outdoor space, but also reduces the visual height and massing of the building from ground level. Exteriors would be clad in a mix of traditional and modern materials, including steel accents that are offset by the warmth of white stained cedar shingle siding and solid wood entry doors.
Shrouded window surrounds and balcony door openings would animate the west façade, while simultaneously providing a shading device to help manage solar heat gain. A cantilevered brise-soleil would be used on the south façade, separate from the main massing, for the same purpose.
Inside, the development would have a total floor area of 3,944 square feet divided into three units. The north and middle units would be 1,197 square feet and the south unit would be 1,550 square feet in size.
