110 Cottingham Street - Once-in-a-Lifetime Summerhill Masterpiece. Welcome to Summerhill, Toronto - where timeless elegance dances with urban vitality. Tucked at the very end of the coveted north side of one of Toronto's most legendary streets lies 110 Cottingham Street - a rare, one-of-one four-bedroom, four-bathroom, three-storey semi-detached home on an exceptional twenty-six by one hundred sixty foot lot. Passionately curated and meticulously cared for over thirty years, this is a true urban oasis and generational opportunity. Boasting one of the deepest and most desirable lots in Summerhill, the property is framed by towering mature trees along the eastern boundary, creating a breathtaking natural canopy of beauty, shade, and unparalleled privacy. Laneway parking leads to a one-and-a-half-car garage with legal capacity for two vehicles - a standout convenience. Inside, the rare three-storey layout offers gracious proportions and abundant natural light. The second floor features three well-appointed bedrooms, including one with a serene south-facing balcony enveloped by the mature tree canopy - your private retreat for morning coffee or golden-hour moments. The third-floor primary suite is a sanctuary unto itself, complete with a dedicated lounge area perfect for unwinding, reading, working, or personal wellness. The showstopper is the fully finished, professionally dug and underpinned basement with a full kitchen, bathroom, and separate walk-up entrance. This versatile, self-contained space is ideal for multi-generational living, an income suite, home gym/entertainment lounge, or flexible family use. The lot is also well-suited for potential laneway home development (subject to approvals).
