About this home

Sayville New Listing — Space, Flexibility & Endless Possibilities This expansive Sayville home offers remarkable square footage, flexible living areas, and unique features that create opportunities for multi-generational living, work-from-home setups, or simply room to grow. Starting at the rear of the home, you’ll find a bonus room with a full bathroom and a separate entrance to the backyard, opening the door to unlimited possibilities — guest suite, studio, private office, or recreation space. A trap door in the ceiling with a fire ladder provides optional access if a future owner chooses to open the space to the upstairs. The beautifully updated kitchen features a gas stove, a double oven large enough to accommodate a full turkey, rich oak-cherry finish cabinetry with strawberry-style knobs, a French door refrigerator with a catering drawer, and a classic farm sink. Adjacent to the kitchen is a 10×10 work room with shelving — ideal for storage, hobbies, or pantry expansion. A huge 20 x 10 screened-in porch, creating seamless indoor-outdoor living. The main level also includes a formal dining room and a spacious living room with built-ins, perfect for gatherings. Upstairs, you’ll find four bedrooms and a humongous walk-in closet that leads to a bonus room — a standout feature offering multi-generational potential, a private office, guest suite, or creative studio. Inside the walk-in closet is additional storage with a built-in workstation, originally designed during the COVID era and is still incredibly useful today. The fully finished attic, currently used as a playroom, adds even more flexible square footage and expansive possibilities for future use.
