Many duplexes in Toronto are old homes with basement apartment units that are rented to students who can't afford anything better.  

And if it's not a house that just happens to have a basement apartment, it's usually the sad, tired-looking square buildings from the 1970s with cramped kitchens, baseboard heaters, and vinyl flooring galore.

But 19 Devon Rd. is completely redefining what a duplex can look like. 

The living room. 

This three-storey duplex in Toronto's Upper Beaches neighbourhood offers a stunning family home with a built-in income opportunity.

The living room leading to the dining room. 

From the moment you step inside, it's clear this isn't your typical Toronto duplex. 

Skylights above the main stairscase bring in lots of natural light. 

Natural light floods every corner of the home, thanks to floor-to-ceiling windows and strategically placed skylights.

The kitchen and dining area. 

The main floor's open-concept design features soaring ceilings, a sleek gas fireplace with decorative shelving, and an oversized marble kitchen island.

Sleek cabinetry and stainless steel appliances elevate the kitchen. 

The European-inspired kitchen is as functional as it is beautiful, with high-end appliances and direct access to a spacious back balcony, perfect for enjoying the outdoors.

The primary bedroom. 

The primary suite, occupying the entire third floor, offers a luxurious retreat.

The kitchenette on the third floor. 

It boasts its own kitchenette, a private balcony, a two-way fireplace, and a spa-like bathroom with heated floors, making it feel more like a high-end hotel suite than a bedroom.

A bedroom. 

For added convenience, the second floor also houses a functional laundry room.

An entrance to the basement unit. 

The second unit is in the basement, but it's nothing like the basement apartment units you're used to. 

A bathroom. 

The fully City-permitted and self-contained apartment includes heated floors, two bedrooms, a full kitchen, two bathrooms, and a separate entrance.

A roughed in kitchen in the basement unit. 

And this house has the potential to become a triplex with another entrance to a space that offers an extra roughed-in kitchen, a bedroom, and a bathroom. 

The open concept main floor. 

This duplex also comes with an impressive list of features, including two gas meters, two hydro meters, and two furnaces, ensuring efficient operation for both the main home and the rental units.

The garage. 

The heated front driveway with a snow-melting system is a wintertime game-changer, while the detached garage and legal parking pad provide ample space for vehicles.

A balcony. 

The home's four balconies also offer plenty of opportunities to soak in the surrounding neighbourhood, making it easy to enjoy the vibrant Upper Beaches atmosphere.

The family room. 

But having a luxury duplex comes at a price.

The back of the house. 

While most duplexes for sale in Toronto right now are under $2 million, 19 Devon Rd. is listed for $2,988,000.
