Welcome to Hilborn House. An iconic architectural residence by the legendary Arthur Erickson, masterfully set on 1.766 acres along the Grand River in Cambridge, Ontario. Commissioned by the Hilborn family and completed in 1974, this extraordinary masonry-built home belongs to Erickson's rare Signature Collection and exemplifies his reverence for landscape, light, and Japanese architectural philosophy. Offering over 6,800 sq.ft, this 3-bedroom, 4-bathroom masterpiece is a study in spatial harmony, where geometry, natural materials, and indoor-outdoor continuity converge. Erickson's use of expansive glass walls, cedar-clad ceilings with structural beams extending over the gardens, blurs the line between nature and structure. Every room draws the outdoors in, whether through treetop balconies, incredible skylights, or floor-to-ceiling windows that reveal forest and river vistas. At the heart of the home, lies a chef's kitchen outfitted with Gaggenau appliances, a center island, and beamed ceilings. The great room, with soaring volumes and abundant light is designed equally for quiet reflection and grand entertaining. A sauna with original mosaic-tiled dual showers, a Lutron smart lighting and shade system, and open-concept yet intimate spaces elevate everyday living into a refined experience. The primary suite opens to a private garden and features a luxurious 6-piece ensuite. The home also features a distinctive cedar deck roof that harmonizes effortlessly with the nature landscape, complemented by a dedicated green space equipped with a drip irrigation system. Outside, curated landscaping, a heated U-shaped drive, and an attached 2-car garage, complete this architectural offering. Rarely does a home of such provenance become available. Hilborn House is not merely a residence, it is a living piece of Canadian architectural history. Interior and Exterior Water Irrigation Systems.
