About this home

A STONY BROOK LIFESTYLE, REIMAGINED. Some homes offer beautiful spaces. Others offer a way of life. This beautifully updated 4 bedroom, 2.5 bath Stony Brook residence offers both along with access to the water through the private 40 Acres Beach Association. Thoughtfully enhanced, the home features a fully renovated kitchen, updated primary bathroom, mudroom, office, mini-split systems, and 12-zone in-ground sprinklers. Significant 2019 improvements include the roof, hot water heater, oil tank, cesspool, and several windows—offering the ease and confidence of a home that has been thoughtfully cared for. Set on over half an acre of beautiful grounds, the outdoor spaces feel like a natural extension of the home with the fenced-in deck with pavilion and separate patio area with a fire pit. Beyond the home itself is a lifestyle that makes this location truly special. Association membership provides access to West Meadow Creek, along with private kayak storage for effortless days on the water. Just minutes away, West Meadow Beach and Trustees Path offer the perfect backdrop for morning strolls, peaceful afternoons by the water, and unforgettable sunsets. Set in one of Stony Brook’s most desirable locations, this home offers a rare combination of thoughtful updates, natural beauty, and an exceptional North Shore lifestyle. This is Stony Brook living at its finest!

About Long

Island

Long Island, located between New York Harbor and the Atlantic Ocean, is a coastal and suburban New York neighborhood with barrier beaches and commuter rail hubs. The neighborhood’s energy concentrates around the Jamaica Station complex, where LIRR platforms, bus bays, and street-level storefronts create a constant current of movement. Housing shifts from compact prewar village centers to postwar capes and split-levels, with marinas and bayfront parks shaping daily routines. Jones Beach State Park and the Long Island Aquarium serve as signature day-trip anchors. The Paramount in Huntington and the Nassau County Museum of Art add a cultural throughline beyond the shoreline. Farm stands, delis, and small main streets stitch together a landscape defined by parkways, dunes, and bays.
