This two-storey house in downtown Toronto was built in the 1930s with small, dark rooms and limited views to the outdoors. Homeowners Christy and Kevin aimed to maintain the appearance of their home from the street, while transforming the interior into a practical, contemporary living space filled with natural light. One side of the house’s gabled roof was ‘lifted’ to allow for a linear skylight to run through the centre of the house above the second floor hallway. Light brings energy into this part of the house and radiates through a tall open space. Unlike conventional houses, the hallway is not a ‘negative space’; it becomes a place where things happen with modest rooms radiating from it. Influenced by the sculptures of the postwar artist, Louise Nevelson, and the interiors of early modernist architect Adolf Loos, rooms contiguously merge or relate to each other with anterooms, interior windows and open floors, creating an unusual experience of vertical and horizontal connectivity. Walls erode and wrap into closets or other rooms. In some cases they are notched or sliced to filter light from one room to the next. At the home’s rear, a cantilevered box pushes the five-year-old son’s bedroom beyond the brick facade, playfully providing him with views of the Victorian fire station next door.
