The Toronto Residence is an exploration of the traditional division of a building. The solidity of the base is maintained while the second floor is light and almost without walls. The kitchen and family room utilize themes vital to ATA’s design concepts: a skylight that filters soft light into the space, and expansive sliding doors that disappear to highlight the seamless integration of interior and exterior spaces. In response to the harsh Toronto winter, the first floor is clad in layers of stone and wood. As the façade lifts up and away from the grade, it is clad in a wood-detailed rain screen. The stone is black and heavy; its color a reference to the Algonquin stone prevalent in Ontario, Canada. The second floor walls follow the profile of the soaring roof above and are finished in white plaster to reinforce the concept of lightness. The pool room is designed with doors that disappear into the walls. The inside wall of the pool borders a 16 foot wide by 5 foot high fish tank that separates the swimming pool from the living room and beyond.
