A $12 million grey box in Toronto never looked this good

Just six years ago, this Toronto property at 50 Teddington Park Ave. was nothing more than a bulldozed patch of dirt.

After sitting on the market for a while, it sold for $3,355,000, which is a lot of money for a 50-by-184-foot plot of land. However, the sale did come with the architectural plans and all the permits needed to build a dream home. 

Several million dollars and five years of construction later, the dream home has arrived—and it's now back on the market for a jaw-dropping $11,995,000.

The foyer. 

From the outside, the 7,655-square-foot house looks more like a modern fortress with its boxy shape and grey concrete walls.

The primary ensuite. 

But don't be fooled by the stoic exterior. This grey box is not only stunning, but it's very luxurious.

The dining room. 

Designed by architect Laith El-Bahrani, with handcrafted bronze panels across the façade, you know this isn't your average new build.

The recreation room in the basement. 

"I wanted to make this a home that was architecturally very sound. You know, classic lines with a contemporary feel and built in the most energy efficient manner," the owner told blogTO.  

A home office. 

And once you step inside, it's clear that 50 Teddington Park Ave., aka "Infinity House", isn't just showing off.

The family room. 

From its net-zero energy efficient build to the seamless connection between the indoors and outdoors with design elements extending to the horizon and the sky —it's a masterclass in modern design-meets-function. 

"The creativity of the architect is what makes the house unique," said the owner. 

The living room. 

The entryway is dramatic, featuring a marble-slab fireplace and a floating staircase suspended between glass panels and a limestone feature wall.

The open-concept main floor. 

But the drama doesn't stop there. 50 Teddington Park Ave. boasts four bedrooms, eight bathrooms, and a breezy, open-concept layout, which is in part how it got its nickname. 

The view into the backyard. 

Right off the kitchen is a NanaWall (a retractable wall made entirely of glass panels) that opens up to the backyard and makes the house feel like it goes on forever.

The backyard. 

Out back, you'll find a heated pool, custom gardens, and multiple terraces perfect for lounging or hosting.

The kitchen. 

The kitchen is equally showstopping, with integrated cabinetry, stone counters and backsplash, and a full suite of high-end appliances. There's also a pantry and a servery, because no luxury mansion would be complete without one. 

The upstairs hallway. 

Upstairs, the second floor is bathed in light thanks to some expertly positioned architectural glazing, leading to four bedrooms.

A bedroom. 

And in case you were wondering, yes, each bedroom comes with its own ensuite.

The primary bedroom. 

The primary suite could almost be mistaken for a boutique hotel with its spa-like ensuite and sound-dampening fabric wall. 

The wet bar. 

And then there's the basement.

The gym and wine cellar. 

It’s stacked with a media lounge, a full wet bar, a climate-controlled wine cellar, a home gym with steam spa, and—naturally—a nanny suite with its own bathroom and laundry room.

The back of the house. 

50 Teddington Park Ave. also boasts radiant heated floors, an elevator, a snowmelt system for the driveway, and a two-car garage with its own heated storage level.
