Located in the city’s up and coming Southwest neighbourhood this 300 m2 detached house hides a rich spatial complexity behind its tough working class faÃ§ade. Turning to the neighbourhoodâs post-war veteranâs home as its formal point of departure, the architects set out to make a house that simultaneously fits in and stands out from its heterogeneous context without resorting to mimicry and without sacrificing the contemporary nature of the project.
The principal challenge lay in bringing light to the living spaces given the tight nature of the lot and the availability of direct sunlight limited to its center. By flipping the traditional vertical hierarchy found in most two storey homes and by carving out a series of spaces from the house’s volume, the project was able to address the need for exposure to direct light and concerns about maintaining privacy. By bringing the living spaces upstairs, the house maximizes direct sunlight where it is needed most. By carving out of the houseâs volume, the light available at the center of the lot is drawn down into the heart of the house and additional private outdoor spaces are provided for each room.
One of the most striking features of the house is the staggered central outdoor courtyard, created to funnel light all the way down to the houseâs lowest level. All the rooms have access to this central space. Full height windows at different levels provide a theatrical quality to the courtyard space and foster for the homeowners an awareness of each otherâs movement throughout the house.
The courtyardâs design also prioritizes the use of passive solar energy. The spatial transparency and open central courtyard allow for a deep penetration of natural light and for efficient natural ventilation and movement of air in the protected microclimate. In parallel to the courtyard, the stacked staircases combined with a north-facing opening at the top provide a cooling chimney effect inside the house. The house maximizes south facing glazing for direct solar gain in winter, and limits glazing on the north faÃ§ade. The radiant concrete floors also serve as a small thermal mass helping to mitigate exterior temperature fluctuations.
On the exterior, the house is restrained, light and monochromatic, emphasizing overall form over components and details. To unify the shape the architects sought a material in a natural colour that could serve as both roofing and wall claddingâ a standing seam aluminium cladding. Flat concrete panels painted to match the colour of the metal cladding were used as subtle accents around doors and windows. In contrast to the cool vertical surfaces, houseâs many terraces are clad in warm IpÃ© decking, highlighting these outdoor extensions of the living spaces.
In sharp contrast to the spatial complexity created by the central courtyard, the interior is also kept uniform, strategically articulated with warm touches appearing in the millwork and central stair. Pale, mat polished concrete floors and unarticulated white walls place the focus on the homeownersâ collection of art and design objects. The kitchen is simply organized around two elements – the island and the storage wallâ both constructed from the same material: heat-treated white oak. The rich chocolate colour of the wood cuts itself out from the white walls and pale grey floor.
Moments of contrasting exuberance are also offered up in the darker, graphic tones of the bathrooms and in the changing vegetation visible through the windows perforating the exterior of the house. These architectural moments contribute to the houseâs sense of theatricality.
