This house in the Junction neighbourhood of Toronto was in need of a total overhaul - structurally as well as functionally - and in a way that maximized the quality of light possible with the house's north-facing orientation. The main floors of the house were gutted, and a small addition to the third floor was added to create an open media/workspace away from the bedrooms and entertaining spaces of the lower levels. Direct light was not possible along the length of the house, so the shadows were used instead to animate spaces. Internal views through the three levels of the house were opened up by increasing the floor openings around hallways and stairs, and a perforated steel guard was used to play with the light travelling through it. The large window at the front of the house received an exaggerated window "frame" at the exterior, which works as a screen for heat gain or a lens for viewing through.
