$5.5M gem of a Toronto home was designed by pair of legendary architects

Toronto has no shortage of architecturally interesting homes, but it's not every day you come across a house designed by the same architects responsible for some of the city's most iconic buildings.

And that's exactly what makes 128 Old Forest Hill Rd. so interesting.

The sprawling Forest Hill South residence was designed by world-renowned architects Raymond Moriyama and Ted Teshima, the names behind some of Toronto's most recognizable landmarks.

The foyer. 

Their firm, Moriyama & Teshima Architects, is responsible for the Toronto Reference Library, Ontario Science Centre, Scarborough Civic Centre and Bata Shoe Museum, not to mention Science North in Sudbury and the Canadian Embassy in Tokyo.

The open-concept main level. 

So, naturally, you'd expect a house designed by them to be something pretty special. And it is. Although it's also a bit of a time capsule to the era of Postmodern architecture the pair of designers are best known for.

A bedroom with a built-in planter. 

The custom-built home boasts more than 8,791 square feet of living space, with soaring cathedral ceilings, massive skylights and enough indoor greenery to make you feel like you've wandered into a particularly luxurious botanical garden.

The indoor gardens. 

Much like the Toronto Reference Library, which is famous for its soaring central atrium and abundance of natural light, this house makes a point of bringing the outdoors in.

The atrium with plenty of plants. 

There are indoor gardens scattered throughout the home, enormous windows overlooking the property and skylights that flood the interiors with sunlight.

A view downstairs. 

The result is a house that feels almost more like a public architectural landmark than your average multimillion-dollar Toronto mansion.

A bedroom with built-ins. 

Of course, some of the interiors are also very much a product of their time.

A family room with a fireplace and built-in bookcases. 

There's plenty of stone, dramatic angles and architectural details that probably seemed incredibly futuristic when the house was first built.

A sitting room with a fireplace. 

And while some buyers might appreciate the retro-modern aesthetic, others will probably be itching to renovate.

A bathroom. 

In fact, the listing itself encourages buyers to update the dramatic interior layout, which is a pretty good indication that the home could use a little TLC.

The sitting room. 

Still, there's no denying the scale of the place.

The kitchen. 

The main floor features a large kitchen, expansive living and dining rooms, and a private library.

The primary bedroom. 

Upstairs, the primary bedroom comes with its own private sundeck overlooking the gardens and a spacious ensuite.

The other primary bedroom. 

There's also a second primary suite with a separate entrance, making it ideal for guests, extended family or anyone who likes having a little extra privacy.

An office encased in glass blocks. 

But arguably the most impressive part of the house is downstairs.

The indoor pool. 

While most Toronto homes are lucky to have a finished basement with a decent-sized rec room, this one has an entire indoor tropical resort.

The primary bedroom ensuite. 

The lower level features a sprawling solarium with a heated in-ground swimming pool surrounded by indoor gardens. There's also a full bar, exercise room, change rooms and a sauna.

Basically, you could spend an entire Canadian winter down here pretending you're on vacation somewhere tropical without ever leaving your house.

A sitting room with soaring ceilings. 

And considering how miserable Toronto winters can be, that's a pretty compelling selling point.

The backyard. 

Also, since the backyard is surprisingly small for a property of this size, the indoor gardens definitely make up for that. 

The backyard. 

Beyond the architecture and amenities, the home is also located just steps from Eglinton Avenue and close to some of the city's most prestigious schools, shops and restaurants.

A bedroom or home office with built-in furniture. 

Of course, owning a piece of Toronto's architectural history doesn't come cheap.

Another bedroom or office space with built-in furniture. 

128 Old Forest Hill Rd. is currently listed for $5,500,000.

And while that's a hefty price tag for a house that could probably benefit from some updating, you're not exactly buying a cookie-cutter mansion.

The kitchen. 

You're buying a home designed by two of Canada's most celebrated architects, complete with its own indoor swimming pool and a whole lot of architectural character.

The back of the house. 

Which, depending on how you feel about the interiors, is either an incredible opportunity or a very expensive renovation project.
