Situated in one of Niagara-on-the-Lake's most admired settings, this remarkable property offers a rare combination of scale, character, privacy, and location. Set on nearly an acre at the prominent corner of Queen and Butler, the home captures beautiful outlooks across the golf course (the oldest golf course in Ontario, and one of the oldest in Canada) toward Lake Ontario, all within steps of the shops, restaurants, and charm of Queen Street. The classic white clapboard residence offers more than 5,500 square feet above grade and has been thoughtfully restored, renovated, and expanded to create a warm and inviting home with generous principal spaces. Gas and wood-burning fireplaces add character throughout, while multiple walkouts create an effortless connection to the gardens and outdoor living areas. The property also includes a separate annex, offering excellent flexibility for guests, family, or private work space, with a bedroom, living and dining area, kitchen, and den or second bedroom. The annex was originally converted from a two-car garage, and it could be converted back. Outdoors, the grounds feel like a private retreat. Mature trees, English-style gardens, flagstone patios, a koi pond with bubbler fountain, and a large inground pool create a series of beautiful spaces for relaxing, entertaining, and enjoying the sun throughout the day. A special offering in one of Niagara's most desirable locations, this property would be equally well suited as an elegant year-round residence or as a memorable getaway for gathering with family and friends. Enjoy all that the Niagara Region has to offer; the Shaw Festival, golf, biking, boating, wineries, and more!
