18754 Heart Lake Road
A jaw-dropping architectural statement in the heart of Caledon!
This one-of-a-kind residence blends world-class design, natural beauty & uncompromising craftsmanship across 10,300 square feet of living space. Designed by Kariouk Architects with interiors curated by the renowned Karin Bohn, the home has been celebrated in films, fashion shoots, and multiple design awards, standing as a true icon of modern architecture in Ontario.
The exterior showcases a copper roof and natural slate stone siding wrapping both the façade and select interior feature walls-materials chosen for their rarity, permanence, and sculptural quality.
Inside, the atmosphere is defined by floor-to-ceiling windows, dramatic lighting and solid white oak tongueand-groove ceilings. The raised ground-floor design allows for continuous transom windows around the perimeter, filling the lower level with natural light. A large central floor opening connects the two levels visually and spatially, framing the home’s main fireplace and creating a dynamic double-height volume.
Throughout the home, you’ll find extensive custom millwork, steel beam and suspended walkways and dramatic vaulted ceilings with ambitious angles that celebrate the artistry of structure and form. The oak interior doors with oil-rubbed bronze hardware add a warm, tactile contrast to the sleek architecture.
The gourmet kitchen features Gaggenau appliances and is complemented by a secondary prep kitchen/ pantry designed for seamless entertaining.
Beyond the interior, an impressive covered deck-integrated into the roof system with Ipe floors and built-in speakers, oriented toward stunning elevated views.
Outdoor living continues with a fire pit, hot tub and inground pool, all set against almost 100 acres of private, forested land-providing tranquility, privacy and notably reduced property taxes. This is not simply a home-it is a work of art, designed for those who value architecture, privacy and the seamless connection between design and nature.
