Seaside open air gated estate with studio-guest cottage and generator. Discover your own secluded island paradise in this enchanting 3.2-acre waterfront estate secure in a community of grand estates at the tip of the Centre Island. Radiating a romantic sense of timeless beauty and impeccably maintained, the five-bedroom, four-and-a-half-bath main house, with its myriad of French doors and windows, sets atop a hillside with spectacular vistas of Oyster Bay. A few steps below it, is an inviting kidney-shaped inground pool with spa and large brick patio, and a little further down at water's edge, is a delightful guest cottage with deck and dock. At the top of the hill, a large level paving-stone parking courtyard and a neighboring service courtyard, accessing a two-car garage, offer ample parking for guests. Located at the far end of Centre Island, home to many grand homes along with summer cottages here and there, this special retreat is about a six-mile scenic drive around Oyster Bay or about three-fifths-mile boat ride to the quaint village of Oyster Bay, where you can enjoy dining, shopping, and catching the train to the city just over an hour away. The Locust Valley area, known as the 'New Hamptons" by those in the know, with its many venues for entertainment and sports, is also about six miles away. With the charming ambiance of an ivy-covered French country home with slate-like mansard roof, this delightful stucco getaway welcomes guests from a bluestone walkway and terrace, through an arched glass door, into a sun-drenched two-story grand hall with gleaming hardwood floors and staircase ascending to a second floor balcony with two walls of French doors and windows and a high tray ceiling. Three delightful guest suites with private baths are off the grand hall that flows seamlessly into a spacious and inviting living room with fireplace and generous sunroom alcove accessing the rear bluestone patio. French doors open to the left into a charming den with built-in bookcases, fireplace, and doors to the patio. On the opposite side of the house, an immense chef's kitchen, featuring ample granite-topped cabinetry, sunny breakfast area, high-end stainless appliances, large peninsula with seating, large walk-in pantry, and a butler's pantry with sink and refrigerator, services a substantial formal dining room overlooking the water through two walls with French doors and windows. Additional French doors open to the living room. On the second floor, a serene and spacious master suite enjoys its own balcony with breathtaking water views, romantic fireplace, two walk-in closets, a luxurious master bath with huge whirlpool tub, shower, water closet, and twin vanity, and a sunny and very private study.
