Price: About $21.2 million A home of music built by a mathematician. This modern home known as Integral House was owned, and designed, by the renowned Canadian mathematician James Stewart. Stewart, famous for his achievements in the field of calculus, was also the author of calculus textbooks that are widely used in the U.S. and Canada. Intensely involved in both the design and construction, Stewart ensured that many interior and exterior details of the house adhered to the principles of calculus, according to the listing agent. With craftsmen from around the world working on the project, the home was finished in 2009 after 11 years of construction. The home has four bedrooms, eight bathrooms, a swimming pool, a spa , a sauna, a gym, a study, and five levels all with elevator access. Stewart, who passed away in 2014, was also a violinist and envisioned Integral House as a home of music and entertaining. The property includes an acoustically perfect concert hall that can accommodate an audience of 300. The building has no windows that open to the outside. Temperature and humidity are precisely controlled by a computer system for the protection of antique musical instruments and preservation of the indoor acoustics.
