Property Description
The McGuire House sits on the crest of a hill in picturesque Stonington Maine overlooking Stonington Harbor. Once the residence of Frank McGuire, founder of the Deer Isle Granite Company, this distinguished home, built circa 1890, beautifully preserves its original character while benefiting from thoughtful modern updates and system improvements made by attentive owners over the years. Become absorbed in an historical account of Stonington while sitting on the front porch and enjoy the captivating view of Stonington Harbor. Subtle reminders of Mr. McGuire's legacy remain, including a granite-lined entry path and impressive slabs of locally quarried granite that form the porch floor. Set on a generous 0.79-acre in-town lot, the McGuire House offers comfortable living space, plenty of storage in the attached barn and garage and mature landscaping. All within easy reach of shops, galleries, restaurants, weekly Farmer's Market and much more. Lovingly maintained and presented in turnkey condition, this exceptional property blends historic significance, coastal charm, and modern comfort.
