About this residence

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 w/interiors curated by the renowned Karin Bohn, the home has been celebrated in films, fashion shoots, & multiple design awards, standing as a true icon of modern architecture in Ontario. The exterior showcases a copper roof & natural slate stone siding wrapping both the façade & select interior feature walls-materials chosen for their rarity, permanence, & sculptural quality. Inside, the atmosphere is defined by floor-to-ceiling windows, dramatic lighting & solid white oak tongue-and-groove ceilings. The raised ground-floor design allows for continuous transom windows around the perimeter, filling the lower level w/natural light. A large central floor opening connects the two levels visually & spatially, framing the home's main fireplace & creating a dynamic double-height volume. Throughout the home, you'll find extensive custom millwork, steel beam & suspended walkways, & dramatic vaulted ceilings w/ambitious angles that celebrate the artistry of structure & form. The oak interior doors w/oil-rubbed bronze hardware add a warm, tactile contrast to the sleek architecture. The gourmet kitchen features Gaggenau appliances & 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 & B/I speakers, oriented toward stunning elevated views. Outdoor living continues w/a fire pit, hot tub, & inground pool, all set against almost 100 acres of private, forested land-providing tranquility, privacy & notably reduced property taxes. This is not simply a home-it is a work of art, designed for those who value architecture, privacy & the seamless connection between design & nature. (id:61366)
