This masterfully restored 1870 estate sits on 5.5 private acres in the highly desirable Ancaster location of Oakhill/Clearview Estates, overlooking the Dundas Valley and the Hamilton/Toronto skylines. Timeless heritage architecture meets refined modern luxury with exceptional craftsmanship and extensive, energy-efficient upgrades, including a 3-storey elevator, renovated kitchen and bathrooms, new windows, plumbing, electrical, HVAC, generator, steel roof, insulation, and exterior stucco. The breathtaking foyer leads to an expansive main level featuring an opulent living room with a stone fireplace, private office, formal dining room, multiple washrooms, walk-in pantry, and a beautifully appointed eat-in kitchen opening to a covered stone terrace. The second level has five spacious bedrooms, including two with ensuites, a sprawling primary retreat, a laundry room, and three additional designer bathrooms. The customizable third floor is currently configured with a bedroom and open living area, with roughed-in plumbing for a kitchen and bath. A finished lower level with a separate entrance offers two additional bedrooms and in-law/guest suite potential. Outdoors, the serene grounds feature an in-ground pool (awaiting reactivation) and a substantial detached stone garage/barn/workshop with 4 oversized spaces and parking for over a dozen vehicles. This impeccably restored estate is a rare fusion of historic grandeur, modern sophistication, and exceptional land, offering remarkable beauty, privacy, and legacy.
