Integral House, Private residence in Rosedale, Toronto, Canada
Integral House is a private residence in Rosedale, Toronto, spanning five levels with curved walls and floor-to-ceiling windows overlooking a ravine. The building contains four bedrooms, eight bathrooms, a home theater, gym, spa pool area, and an elevator connecting all five floors.
Mathematician James Stewart commissioned the building in 1999, with construction completed in 2009 following an extended building phase. The project embodied Stewart's vision of a residential structure integrating mathematics, architecture, and quality of living.
The residence includes a concert hall seating about 150 people, making it one of the first private homes in North America with such an extensive performance space. Musical performances and cultural events take place regularly in this dedicated room.
The property sits in a quiet residential neighborhood with access to park trails exploring the surrounding ravine system. Visitors should note this is a private property and access may be limited.
The building uses 23 geothermal boreholes for temperature control, making it one of the most energy-efficient private residences in the city. These underground systems enable heating and cooling without conventional external units.
