Modern Living, Redefined. Tucked into over 5 acres of Carolinian forest in the Dundas Valley, this architectural triumph offers unmatched privacy, design excellence, and seamless indoor-outdoor living. Crafted by DB Custom Homes and envisioned by SMPL Design Studio, this Net Zero, Mies van der Rohe inspired masterpiece spans 8,107 sqft, with an additional 2000+ sqft detached studio/workshop. Clad in glass, ACM panels, and Shou Sugi Ban siding, its minimalist form is anchored by 115' of 12' lift-and-slide doors and a 3,500 sq ft professionally seeded, maintenance-free green roof, beneath a solar panelled upper level green roof. Inside, soaring 11.5' ceilings and radiant in-floor heating set the tone for refined living. The chef's kitchen features integrated Gaggenau appliances, an 18' island, and hidden pantry with extra fridge and freezer. The two living areas, a formal dining space divided by a 10' three-sided fireplace, a theatre room, dual office nook and gym with Sauna - invite effortless entertaining. A 1,200 sqft creative studio sits just off the oversized two-car garage and mud room. The cantilevered primary suite offers a private sanctuary with panoramic views, a spa-like ensuite, a walk-in closet with dual skylights, a coffee bar, and 24' sliding doors to a heated terrace. Above, a 48" skylight and floating glass floor flood the space with natural light from above. Outside, explore private trails, a spring-fed pond, and an auxiliary building with two garage bays, a bathroom, and flexible workspace - ideal for a studio, guest quarters, or future expansion. Featuring geothermal heating/cooling, solar energy, smart home tech, and approved pool permits, this home is a rare convergence of form, function, and forested serenity.
