Stewart’s passion for calculus can be seen throughout the design of Integral House. The house’s name is inspired by the concept of the integral, which is a fundamental idea in calculus that represents the area under a curve. The house’s curved walls and ceilings symbolize the sine and cosine curves that are integral components of calculus. The house also features a beautiful spiral staircase that represents the mathematical concept of the Fibonacci sequence.
