21 Holly Dr, Edwardsburgh/cardinal, ON K0E 1T1

This home was never built to meet a price point. It was built to be the owner's forever home, with a level of engineering, craftsmanship, and documentation that is never available on the resale market. Set on a private half-acre lot at the end of a quiet dead-end road, this approximately 4,400 sq. ft. custom all-stone residence offers 3 bedrooms, 3.5 bathrooms, an oversized three-car garage with access to both levels, and a fully finished walk-out lower level. The home is constructed with insulated concrete form (ICF) exterior walls and a Legalett engineered heated slab foundation featuring four independently controlled heating zones, delivering exceptional comfort, durability, and energy efficiency. Inside, you'll find custom solid oak cabinetry built with plywood boxes, natural granite throughout the kitchen, bathrooms and laundry room, hardwood and porcelain flooring, 102-inch ceilings on the main level, and a thoughtfully designed layout that balances everyday living with effortless entertaining. The spacious primary suite includes dual walk-in closets and a luxurious ensuite, while the lower level features a large recreation room, a massive, heated workshop, wine cellar/cold storage and abundant flexible living space. A covered deck overlooking the surrounding landscape provides the perfect place to relax and enjoy seasonal views toward the St. Lawrence River. Equally impressive is the documentation accompanying the property, including original construction drawings, engineering information, invoices, specifications, schedules and progress photographs, providing an exceptional level of transparency and confidence that is almost never offered with a resale home. Located within easy commuting distance of Ottawa and minutes from the international bridge to the United States, this is an impossibly rare opportunity to own a home where quality of construction is every bit as impressive as its appearance.
