Situated on a gated ~150x200 ft corner lot in the exclusive Uplands enclave, this 5,500 sqft 5 Bedroom custom estate offers a highly engineered, generational retreat among Thornhill's most significant properties. With the potential to expand or sever the lot to build additional dwellings, this offering is best not to be overlooked. The Bellevue Mansion was custom-built for absolute endurance and security, functioning as a true fortress. Featuring a personal park oasis concealed behind a private perimeter of 400+ mature evergreens and iron fencing, you can have the privacy you deserve with endless possibilities for your ultimate vision. In addition, enjoy the luxury of living across from true Canadian wildlife at the picturesque Oakbank Pond Park. Inside, the all South-facing interiors are flooded with natural light thanks to the large-scale windows, 10-foot ceilings, and crystal chandeliers. The finishes project quiet confidence and exceptional quality: an imported Italian kitchen outfitted with Sub-Zero, Wolf, and Miele appliances, alongside radiant heated floors, Brazilian hardwood, and oversized solid wood doors. Designed for seamless multi-generational living, the floorplan uniquely features the potential for 3 primary suites, with the capability to form more bedrooms if need be. Featuring self-contained wellness and entertainment spaces, the home is complete with a fitness studio, natural wood sauna, walk-in wine cellar, games lounge with a bar, and an executive office with sunset views over the water. Be sure to book your private tour.
