    What's special

    Welcome to 'The Windmill House,' an iconic Grand Dame in the heart of Westhampton Beach's Estate section spanning an entire block from Seafield Lane to Beach Lane. Set on almost two acres, this 19th century estate boasts an eight-bedroom main house attached to a once-working windmill, private guest quarters, gunite pool, Har-Tru tennis court and large pool house with laundry, living room, and full bath. Owned by the same family for the last 60 years, this classic estate is waiting for its next owner to bring it back to its former glory and has the potential to be someone's trophy property. The main house has a charming front porch, original front Dutch door with bullseye glass, original wood floors, beadboard ceilings and walls, three staircases, four working fireplaces, butler's pantry and kitchen with informal dining, elegant dining room, living room, music room, and nautical-style den with wood walls, floor and ceiling. On the first floor you'll also find a powder room and large master bedroom suite with sliders to a private patio. The second floor boasts seven additional bedrooms, four baths, access to the top of the windmill, and lots of nooks and crannies. As if that wasn't enough, the attached guest cottage provides separate utilities, full kitchen, living room, full bath and three bedrooms-the perfect owner's quarters if this property was converted to a bed-and-breakfast. Solid summer rental history. Only 90-minutes to Midtown Manhattan and two minutes to ocean beaches and Westhampton Beach's newly transformed Main Street. The house is being sold "as is."
