Nestled at the end of a quiet cul-de-sac in Thornhill's prestigious Bayview Glen community, 3 Rosea Court offers timeless elegance, complete privacy, and luxurious living on one of the largest and most exclusive estate lots in the area. Set on over 25,000 sq.ft. (0.579 acre) with a 251-foot-wide rear lot line and surrounded by mature trees, this meticulously updated 2-storey residence delivers the perfect balance of comfort, sophistication, and serenity all within an ultra-private enclave of just 15 homes across three exclusive courts, where turnover is exceptionally rare. Fully move-in ready and extensively renovated with over $300,000 in upgrades since 2021, the home features 4 spacious bedrooms upstairs, 1 additional bedroom in the basement, and 6+1 bathrooms, which includes a fully equipped pool cabana with kitchen and bath. The main kitchen boasts custom cabinetry with quartz countertops, premium Sub-Zero, Wolf, and Bosch appliances, and a seamless flow into elegant living and dining spaces. Additional features include hardwood floors, new windows (2021) with 3M security film, two laundry rooms, dual-zone HVAC with HRV, security cameras, and a new roof, garage, and entry doors (all updated in 2021). Outside, enjoy your very own resort-style backyard complete with a saltwater concrete pool (repainted in 2023), full-size tennis court, in-ground sprinkler system, and expansive space for relaxing or entertaining. What truly sets this property apart is its position within a pocket known for some of Thornhill's most impressive estate homes, including several properties across the adjacent courts that sit on smaller lots yet hold values approaching eight digit figures. Whether you're drawn by the prestigious location, the rare large lot size, or the flawless condition of the home itself, 3 Rosea Court is a once-in-a-generation opportunity to live in one of the most admired and tightly held enclaves in the Bayview Glen community.
