Description

Classic Fire Island charm meets endless potential in this spacious 4-bedroom, 2-bath beach cottage in the heart of Ocean Bay Park. Set on an oversized 100x100 lot and just moments from the ocean, this home offers the kind of easy coastal living that makes summers here so special — with plenty of room for a pool.

Designed with a unique and functional layout, the home features two bedrooms and a full bath on one wing, while the opposite side offers two additional bedrooms and another full bath — all centered around a bright, open living space. A sunken living room adds character and creates a natural gathering spot, flowing into the kitchen and dining area for relaxed ente
rtaining.

With both front and back decks, there’s plenty of room to enjoy sunny afternoons, outdoor dining, and cool summer nights. Full of classic beach house charm, this is a rare opportunity to own a timeless Fire Island cottage on an oversized property, ready to be enjoyed as-is or reimagined over time.
