About This Property

Nestled in the highly sought-after S-Section of Stony Brook - a neighborhood treasured for its strong sense of community, tree-lined streets, and exceptional location - this original-owner 4-bedroom, 2-bath ranch presents a rare opportunity to make a truly special home your own.

Offered for the first time since it was built, this home has been lovingly maintained by the original family. While a new owner may choose to update the cosmetic finishes to reflect today's style, the home's solid construction and well-maintained major systems provide an outstanding foundation for the future.

The spacious floor plan features generously sized bedrooms and inviting living areas, highlighted by a sun-filled rear addition that expands the home's living space beyond what is typically found in similar S-Section capes. Whether envisioned as a family room, entertaining space, home office, playroom, or peaceful retreat overlooking the backyard, this versatile sunroom offers endless possibilities.

Outside, enjoy your own private oasis featuring an in-ground pool, perfect for summer gatherings with family and friends. An oversized two-car garage provides ample room for vehicles, storage, hobbies, or a workshop.

Ideally located just minutes from shopping, dining, parks, beaches, and Stony Brook University, this is a unique chance to own a home in one of Long Island's most desirable communities. Bring your vision and write the next chapter of this beloved Stony Brook home.
