Upon entering through the iron gates into the verdant walled garden of 40 Prospect Avenue, one witnesses a stately colonial sitting atop over 17,000 square feet of property with panoramic views of Hempstead Harbor and incredible sunsets. Once inside, you are drawn to the living room with its built-in bookshelves, wood burning fireplace and picture windows overlooking the water and a large backyard with steps leading down towards the beach. The eat-in kitchen has large windows overlooking the boats bobbing in the harbor. The first floor also features a dining room with a fireplace and a full bath. Upstairs, the primary bedroom extends across the back of the house with two closets and great views. There are three other bedrooms on the second floor and a full bath. A stairway leads to the attic with high ceilings offering endless possibilities for use as a gym or great room. The lower level has a den with a wood burning fireplace, a full bath, built-in bookshelves, doors out to the patio and, best of all, expansive views of Hempstead Harbor clear across to the shores of Westchester County. An opportunity like this in Sea Cliff is rare. Seize it while you can!
