House C4

Big makeover brings modern look and function

The house is a three-storey flat roof structure with a two-storey addition in the rear. Flat roofs were chosen not only for the modern appearance but for rain water collection and green roof application. The house, with its modern appearance, is appropriately positioned on the site. Set back slightly from its neighbours, the house takes on a more humbled position in the row of houses

The house is filled with natural light in every space and meets the client’s desire of acquiring spacious living areas to house a young family with three small children on a standard 20×120 foot narrow and deep lot in an established downtown Toronto neighbourhood.
To distribute maximum natural light provided by the skylight above the light-filled central stairwell, the stair guards are glass, and the walls on the second and third floors have either glazed partitions or glazed clerestory openings facing the stairwell. The open-concept ground floor layout, with large floor-to-ceiling sliding glass walls spanning the width of the house at both ends, provided a series of light-filled, spacious and fluid-living dining and cooking spaces. Great care was also given to have a lower level that is light flooded and does not feel like a basement.
