Don Mills Ravine Home designed by Altius Group of Companies serves as a “cottage in the city” for a couple that loves to host and entertain. The generous lot falls away to a forested ravine, and the design takes full advantage of the private 5,000 sq. ft. urban oasis. Public spaces make up the length of the rear side of the house with expansive views and access to the backyard, pool, and terraces. Photography by John doe.
