Integral House

Integral House in 2016

Integral House is a private residence located at 194 Roxborough Drive in the Rosedale neighbourhood of Toronto, Ontario, Canada.[1] The project was commissioned by mathematician James Stewart as a residence incorporating a performance space, and was designed by Brigitte Shim and Howard Sutcliffe of the Toronto architectural firm Shim-Sutcliffe Architects. The name of the house is derived from the mathematical integral symbol, commonly used in calculus; Stewart's wealth derived from his authorship of widely used calculus textbooks. It has won several architectural awards, including a 2012 Governor-General's Medal in Architecture.[2] Glenn D. Lowry, director of the Museum of Modern Art, said of Integral House, "I think it's one of the most important private houses built in North America in a long time."[3]

The house went on sale in the autumn of 2015 after Stewart's passing in December 2014.[4] It was sold in 2016 by Sotheby's. At that time it had been speculated that the buyers were musicians Chantal Kreviazuk and Raine Maida,[5] although when the house was re-listed for sale in 2019, it was reported that the buyer had been Mark Machin, a British banker and then-president of the CPP Investment Board who has purchased the property for C$15 million in 2016 and lived there with his wife and children.[6] The house was sold in 2020 for a slightly-higher C$18.5 million.[7]
