An exceptional opportunity in the heart of Yonge & St. Clair. Set on an impressive extra-deep lot, this substantial 3-storey semi-detached century home offers over 3,000 sq ft of living space, generous principal rooms and a wealth of architectural character. Thoughtfully maintained and improved over the years, every renovation has been undertaken with an emphasis on quality materials, fine workmanship and meticulous attention to detail. The home features hardwood floors, an inviting open-concept living and dining room, and a separate eat-in kitchen with granite countertops, a matching granite table, large windows and premium Miele and Sub-Zero appliances. Four bedrooms provide excellent flexibility, including a spacious primary with walk-in closet and semi-ensuite access, and a versatile 2nd-floor bedroom, currently used as an office, with fireplace and custom built-ins. The 3rd-floor bedrooms offer additional privacy, including one with sliding-door walkout to an expansive rooftop deck. The beautifully finished lower level features a recreation room with a full-wall entertainment unit, wet bar with wine fridge, 3-piece bathroom, laundry/utility room and separate walkout entrance. Outdoors, discover a truly special mature woodland garden, where towering evergreens, perennials, shrubs, ivy and professionally designed stone patios create a remarkably private, tranquil oasis. Just 1 minute from Yonge Street, yet the backyard feels worlds away, like a retreat in the countryside. Enjoy multiple outdoor living spaces, including a deck off the living room and a rooftop terrace. A rare, city-permitted double-wide private driveway accommodates 2 cars. Ideally situated between St. Clair and Summerhill subway stations, with easy access to Yonge Street's shops, restaurants and amenities, and some of Toronto's most prestigious private schools. A wonderful opportunity to enjoy space, privacy and convenience in one of midtown Toronto's most desirable neighbourhoods.
