The Integral House - Canada’s Most Unique Home

The Integral House, completed in 2009, is globally recognized as Canada’s most unique home, and also perhaps one of the world’s most fascinating and distinctive luxury properties on the market today.

The Concept

Located in Toronto’s affluent and established Rosedale neighborhood, The Integral House combines modern luxury with distinctive architectural details, including a myriad of curving lines and walls, earning it the nickname “The House That Math Built.”

As you arrive at the front entrance, you’ll feel as if you’ve left the urban environment of surrounding Toronto and are instead in a wooded, natural oasis. What you can’t see from the front of this home is how truly magnificent its ravine location is, and it’s this ravine that defines much of the design concept of this luxury property.

Approaching The Integral House you’ll see a modern structure that appears to be a modest two-story home, where the first story lays out your introduction to the curving lines and oak structures that you’ll come to find throughout this architectural icon. The wooden elements of the home’s front exterior are indicative of the forested areas that surround this property.

Perched gracefully atop the solid wooden first story is an ethereal glass structure, which seamlessly combines with the sky above and also features soft, gentle lines, allowing it to appear as if it’s floating. In the evening, light radiates from this glass structure, a custom design created by a team of Spanish artists, and gives the home a luminescent glow.

While the exterior design of The Integral House exudes a sense of contemporary harmony and distinctive design, it’s what you’ll find when you enter the front doors that will truly take your breath away.

The curves of the exterior are carried throughout the home’s interior, which is an homage to the original owner’s love for mathematics, and particularly calculus. While the exterior appears to be only two stories, once inside you’ll discover a design secret: it’s actually a five-story home with four bedrooms, an astounding eight bathrooms, and a passenger elevator with service to each level of the home.

Designed to be not only a home but also a world-class performance space and artistic showcase, as you walk into the 17,000 square foot Integral House you’ll find massive, open spaces and stunning views of the Rosedale Ravines from three sides of the house.

Walls of glass and oak fin-like structures surround you, which has led this home to be described as one of the most important private homes in North America in an interview with Glenn D. Lowry, director of the New York Museum of Modern Art.

The Integral House has also won several prestigious architectural awards, including the American Institute of Architects’ Honor Award for Interior Architecture in 2012, and in the same year the Governor-General’s Medal in Architecture.

While the overall aesthetic of The Integral House is sleek, modern and streamlined, the home’s design also instantly evokes the feeling that the outdoors and the natural beauty of the surrounding 182,986 square foot property is a pivotal part of the home’s interior.

The curves and integration of nature evoke the sense this home isn’t just a structure, but has its own soul and is a space that’s constantly evolving.

The home took six years to complete, because of the complexity of the calculus-based design, with construction finally completed in 2009.

The Performance Space

The home’s original owner, Dr. James Stewart, had not only a love for mathematics but also for music, and he poured this passion into the creation of a truly one-of-a-kind concert hall replicating the acoustics and design of some of the best performance spaces in the world. This private hall has hosted the likes of composers such as Phillip Glass and Steve Reich, as well as entertainers like David Bowie and Iman.

Each of the 97 rippling wood fins that define this home, and in particular the concert space, are not only aesthetically fluid and representative of a sense of constant movement, but they’re also in place to provide the perfect acoustics and sound environment in the home’s concert hall.

The cavernous concert hall, of course with epic ravine views, features lower level seating for about 200 guests, and there are upper-level balconies, much like you would find in an opera house, which can be used for seating about 150 more guests.

Luxury Paired with European Sensibility

As this home is designed to be an entertainer’s dream, it includes practicalities in the upper-level balcony areas including cocktail lounges, a bar, and a catering kitchen.

As well as the catering kitchen, the home features a contemporary gourmet-style kitchen with a streamlined European-inspired design sensibility. The outdoors again comes into play in the kitchen with the use of richly patterned stone, and, of course, the incredible views.

State-of-the-art, professional-grade appliances pair with one-of-a-kind pendant light fixtures and in-kitchen seating comes in the form of the centrally located island and bar, where you can imagine gathering with your closest of friends after an evening of entertaining or hosting.

While less obvious, there remains a focus on soft, curving lines even in the kitchen, which is a departure from the typical straight, unbending lines typically seen in modern architecture.

The kitchen of The Integral House manages to be both practical and beautifully designed.

Artistic Elements

One of the artistic showpieces of this home is the commissioned blue glass staircase. This blown glass structure, created through a collaboration of artist Mimi Gellman, Shim-Sutcliffe Architects, and structural engineer David Bowick, is a showpiece of functional art.

The glass staircase is constructed of blue glass rectangles and supported by stainless steel cables, while the translucent glass is illuminated by the natural light, which pours in from the skylight above, creating a celestial experience.

As a lover of not only music, but all things related to the arts, the home’s creator Dr. Stewart wanted to add not only one of the world’s most amazing concert spaces, but also an art gallery, which effortlessly leads to a study, featuring a conference area.

The home’s office space is more private and envelops you with views of the outdoors, making work or hours spent in contemplation, feel tranquil and enjoyable.

Scenic Private Spaces

While much of the home is designed around entertaining and performance, the private spaces in The Integral House are no less spectacular. There are four bedrooms in this expansive home, each of which is well-separated from the others, to create a sense of privacy that’s perfect for hosting overnight guests.

The bedrooms and bathrooms continue to highlight the relationship between the inside and outside, with vast walls of glass serving as the rooms’ primary focal points.

The master bedroom includes one of the home’s three wood-burning fireplaces, creating a warm, inviting retreat during the cold Toronto winters.

The master bathroom features a glass shower that feels almost as if has no enclosures at all, and to the side of this open shower masterpiece is a soaking tub built into the floor, offering again, the ravine views that make this house so visually inspiring.

The master bathroom is a spa-like retreat where hours can be spent luxuriating.

The SPA Level

The lower level of The Integral House continues the feeling that the private areas of this home are a retreat, perfect for reviving your soul and spending time doing the things you love in an remarkable setting.

The entire lower level of the home is designated as the spa level, and features a state-of-the-art exercise space, a wet sauna, changing areas and a powder room, while the showpiece of the spa level is an indoor exercise pool, set against the backdrop of a 30-foot glass wall.

During the summer months this glass wall drops below pool level and unites the pool with the outdoors. The pool also includes a hot tub and an optional waterfall feature that rushes along the adjoining wall when activated, creating not only a soothing visual element, but also calming sounds.

You can opt to venture out onto the stone patio, which puts you right in the midst of the ravine into which this home was constructed, bringing you a sense of peacefulness and a closeness with nature as you’re surrounded with trees.

Sustainable Design

In an homage to the surroundings of The Integral House, the soaring five-story design of the back of the home replicates the climbing ravine into which this home was sculpted.

On the ravine side, each of the home’s five levels is designed to not only reflect, but also seamlessly interact with the natural elements. The home’s base represents the wooded forest floor and it gradually ascends to the upper glass level, a reflection of the airy tree tops and sky, with each level continuing to display the original owner’s love of curved lines and the inherent movement of nature.

Sustainability is woven into almost every aspect of this home’s design, including a geothermal heating system and an eco-friendly rooftop garden area.

The integral house also features an impressive five car garage, and because Toronto winters can be quite chilly, there is a built-in heating system for the walkways and the driveway.

Rosedale—Toronto’s Most Desirable Neighborhood

Along with the visually exceptional design of The Integral House, it also features a unique location, situated in the Rosedale neighborhood of urban Toronto, which is a leafy, green-filled area with a collection of traditional, brick homes. Despite the ornate, traditional architecture that makes Rosedale distinctive and sought-after, The Integral House has managed to become the neighborhood’s crown jewel.

Rosedale has been named as Toronto’s most stylish and desirable neighborhood for more than a century, and it’s also where many of the city’s most notable and wealthy residents call home, known for its abundance of parks and proximity to Toronto’s hottest shopping and dining.

Although the location is largely defined as urban, The Integral House, thanks to its ravine setting and wooded surroundings, feels worlds away from the city hustle and bustle and allows you to retreat to your own private sanctuary each time you return home.

The Integral Man- A Feature Documentary

The Integral Man is a feature-length documentary, written and directed by Joseph Clement of Auratic Media that puts the spotlight on this world-famous home, and also delves into the personal story of Dr. James Stewart. Dr. Stewart, despite his contributions to the arts, music and culture, was relatively unknown at the time of his death on December 3, 2014.

This brilliant calculus mathematician is the most published author of mathematics and calculus in the world, but was also a concert level violinist, and he played a valuable role in Canada’s gay rights movement.

Dr. James approached Shim-Sutcliffe Architects to design and create his vision of a groundbreaking residence, which is how The Integral House came to be. Part concert hall, part architectural wonder, the house has served as a pilgrimage for some of the world’s most influential architects, musicians, artists and philanthropists, and has also served as a backdrop for amazing concert performances.

When Dr. James was diagnosed with terminal cancer a year into the making of The Integral Man, he made it his mission to live out his remaining days as a bold testament to his convictions and life’s passions.

Filming of The Integral Man documentary will continue throughout 2015 and is slated for a completion date in Spring 2016.
