507 Riverdale Avenue SW

Offered at $3,350,000


Unprecedented quality and construction on a 75’ lot in an amazing location overlooking the Elbow River. Mike Holmes “made it right” when creating this low-maintenance, energy-efficient, luxury home. Behind the double-wide offset walls, that allow for extra insulation, you’ll find mold and moisture-resistant “blue wood”, spray foam and noise-dampening insulation, and an abundance of extraordinary construction and design details throughout.

As you cross the threshold into this home you are met with a multi-story living wall that is not only beautiful but it helps to oxygenate and purify the air. In the open living area, with a clean-burning fireplace, the floor-to-ceiling glass wall fully opens to the sunny south-facing deck for the ultimate indoor-outdoor living space. Relax and entertain in the indoor or outdoor kitchen with a stone pizza oven, both with high-end appliances. Wolf and Miele appliances, granite countertops, hydroponic herb fridge, butler pantry with second dishwasher and so much more.

The second floor has three bedrooms, a gym (that could easily be converted to another bedroom), and a laundry room. The third floor is the master retreat with a meditation nook overlooking the river, extensive closet and storage systems, and an ensuite with floor-to-ceiling granite tile. Just off the master bedroom is the main office with accordion glass doors to the third-story balcony with views of the river and valley.

A concrete slab and 500lb barn door separate the home from the basement providing a soundproofed space where the action and noise of a movie or game in the media room won’t be noticed throughout the house. The home is equipped with an elevator to all levels and has been designed to be fully wheelchair accessible.

The oversized triple garage (with a green roof) is large enough to accommodate car lifts so inside parking could be doubled if required. Built like no other - eco-friendly, sustainable, durable, and low maintenance - this home has an extensive list of features beyond what is mentioned. An incredible location across from the Elbow River steps from the river pathways, Stanley Park and so much more. The home also offers access to some of Calgary's top inner-city schools including Elbow Park, Rideau, and Western Canada High School.
