Incredible Water Views, North Haven

First time on the market, 4 Mashomuck Drive is a rare offering in North Haven Manor, a private waterfront community. Tucked at the end of a quiet cul-de-sac and adjacent to protected community land known as the Esplanade, this special property enjoys direct access to Sag Harbor Bay and forever-protected bay views. Built in 1970 and thoughtfully updated over the past several years, improvements include a new roof, windows, mechanicals, kitchen appliances, and baths. This classic shingle-style beach home offers a gourmet kitchen, a formal dining room opening to a waterview patio, and an eat-in kitchen with access to a large entertaining deck overlooking the bay. Interior living spaces also include a formal living room and media den, along with five bedrooms, including primary suites on both the first and second floors. A roof deck, beautifully maintained and landscaped grounds, and a charming courtyard complete the setting. A true legacy property to be enjoyed for generations.
