About this home

Shelter Island Heights Icon Gracefully positioned in the heart of Shelter Island Heights, this timeless residence has been thoughtfully renovated and restored to honor its original character while seamlessly incorporating today's modern comforts. Rich in architectural charm and classic detail, the home offers an elegant blend of historic beauty and refined living. A gracious, oversized covered porch welcomes you upon arrival, providing the perfect setting to relax and enjoy the property's elevated position and picturesque water views. Inside, a warm and inviting foyer opens to beautifully proportioned living spaces, where natural light, period details, and a sense of understated sophistication create an atmosphere of effortless elegance. Toward the rear of the home, a formal dining room and well-appointed kitchen serve as the heart of the residence. Expansive windows and French doors bathe the interiors in natural light while creating a seamless connection to the surrounding landscape and outdoor living spaces. The second level is highlighted by a spacious primary suite featuring a generously sized bath, accompanied by two well-appointed guest bedrooms designed for comfort and privacy. The third floor offers a versatile retreat, ideal as a media room, den, home office, or additional gathering space for family and guests. Outside, the beautifully landscaped grounds provide a private sanctuary framed by mature trees and established plantings, creating a tranquil setting for relaxation and entertaining alike. Ideally situated just moments from the coveted Shelter Island Heights Beach Club, tennis courts, golf, marinas, shops, and beloved local restaurants, this exceptional offering presents a rare opportunity to own a meticulously restored home in one of Shelter Island's most desirable and historic neighborhoods.
