About This Home
Discover a rare bayfront offering in Westhampton Dunes, where timeless Hamptons cottage character meets exceptional potential. This multifamily property presents a unique opportunity to enjoy its inviting, relaxed elegance as is, or thoughtfully reimagine it into a truly one-of-a-kind waterfront retreat. Set along approximately 175 feet of bulkheading, the property enjoys sweeping open-bay views. The main cottage features three bedrooms and two bathrooms, an eat-in kitchen, and a generous great room oriented to capture the water views beyond. The home is equipped with air conditioning and heat, ensuring comfort all season. A separate guest cottage provides excellent flexibility, offering two bedrooms, one bathroom, a fully equipped kitchen, and split systems providing both air conditioning and heat. Ideal for hosting guests, extended family, or rental income, the layout allows for privacy while maintaining a cohesive sense of place. Outdoor living is equally compelling, with a private deck overlooking the bay-perfect for quiet mornings, sunset gatherings, or simply taking in the natural beauty of the setting-as well as an outdoor shower, ideal after a day at the beach. With ocean beach access across the street and less than five miles from the boutiques and dining along Westhampton Beach Main Street, this property offers a rare balance of tranquility, convenience, and classic Hamptons appeal.
