A five-storey Toronto home inspired by the concept of integrals and its late owner's love for music has been put on the market for $23million.
Integral House was commissioned by the late mathematician James Stewart, who passed away in December last year, to allude to the curves of calculus, but also function as a performing space.
The house, in Rosedale, Toronto, took six years and cost $24million to build, and includes a pool, performance space, a roof garden and geothermal heating.
Incredible design: Integral House, which was commissioned by the late mathematician James Stewart, is on the market for $23million
Hidden dream: The house is built into the hillside of the ravine, so just the two top floors are visible from the street
The Stanford and University of Toronto alumnus was also an accomplished violinist and a former member of the Hamilton Philharmonic Orchestra.
'Calculus is the mathematics of curves, and there is an infinite variety of them. Curves are what make the world go around,' he told Azure Magazine.
One man's idea: Dr James Stewart wanted Integral House to allude to the curves of calculus, but also function as a performing space
Indoor scene: The two top levels are designed to also function as stands for the third floor performance space, and fits 150 people
Famous owner: Integral House was purpose built for Dr Stewart, a Canadian mathematician and author of a series of calculus textbooks used in high schools and universities across the globe
Space to relax: The lowest level is a pool area with an outdoor patio separated from the house wall of glass that can be lowered into the floor
Lost master: Dr Stewart was diagnosed with a type of blood cancer in summer 2013, and died in December last year
Integral House is the work of Toronto husband-and-wife team Brigitte Shim and Howard Sutcliffe of Shim-Sutcliffe Architects, who were commissioned by Dr Stewart after a long search for the perfect architects for the job.
After purchasing the property in 2002, Stewart tore down the original house and construction of Integral House began in 2003 and continued for six years before completion in 2009.
The final cost of Integral House was estimated at $24 million.
The 18,000 square foot house is built into the hillside of a ravine, and only the two top floors are visible from street level. It is set out to be as environmentally friendly as possible and has geothermal heating and cooling and planted roofs.

As well as a pool area with an outdoor patio, the house includes a concert hall that seats 150.
The house has won several design awards, including the American Institute of Architects' Honor Award for Interior Architecture in 2012 and the Governor-General's Medal In Architecture the same year.
Glenn Lowry, director of the Museum of Modern Art in New York, called the house 'one of the most important private houses built in North America in a long time.'
At peace: The master bathroom has a bath build into the floor and a glass shower
Soft: Even in the kitchen , there is a distinct lack of sharp edges, and the light wood panels are seen throughout
Famous: Integral House has been called 'one of the most important private houses built in North America in a long time'
