About this property

A statement in craftsmanship and design, this custom-built residence spans approximately 8,660 square feet above grade and offers an exceptional sense of scale paired with refined, curated finishes throughout. Featuring 5+2 bedrooms, with ensuites and custom built-in closets, the home delivers both privacy and consistency in design. At the centre, a beautifully appointed chef's kitchen is outfitted with top-of-the-line Wolf and Sub-Zero appliances, seamlessly connecting to the surrounding principal spaces. A fully integrated Control4 smart system allows for effortless control of lighting, climate, and media across the home. On the main level, a striking wine display serves as a design focal point, while the indoor pool introduces a rare, resort-style element, offering year-round enjoyment. The lower level is thoughtfully finished with a private movie theatre and a home gym, creating additional space tailored for comfort and recreation. The primary suite is a true retreat, complete with a spa-inspired ensuite and separate his-and-hers walk-in closets, both finished with custom built-ins. Every element of this home reflects a high level of care, from the quality of construction to the cohesion in design, an impressive and well-executed offering from start to finish.
