Utmost privacy surrounded on three sides by land that has been farmed by the same two f amilies since the 1600s. This 6.9 +/- acre estate is bordered on the fourth side by 360 +/- feet of water frontage on Mecox Bay. This shingle-style traditional house with classic gardens truly epitomizes the concept of artisanal fueled craftsmanship. The house was the collaboration of the best talents in their respected fields: Katherine McCoy architect, M en at Work builders, Quincy Hammond landscape architect, Daniel Romualdez interior design, Torie Burke wall finishes, and Donald Kaufman colorist. Taking five years to complete, Listowel truly redefines luxurious living in the Hamptons. The interior and exterior spaces are designed to seamlessly integrate all the modern conveniences yet still maintaining the old world style and sensibility. The home encompasses over 12,000 +/- sq. ft. of living and entertaining spaces including a dramatic two-story library with a fireplace as you enter the front door. The large living room with fireplace features three sets of French doors that open up to the expansive covered porch. The smoking room has a beautiful bay window and a set of French doors onto the eastern facing covered porch. Off the main foyer on the west side of the house is the formal dining room with French doors, fireplace, and hand-painted chinois wallpaper. The butler's pantry leads to the stainless steel chef's kitchen with walk-in pantry and the best appliances available today. The adjacent large gathering room includes 4 sets of French doors opening on to the trellis-covered outdoor living room with a wonderful stone fireplace. Separate, though attached, is the guest cottage which features a complete informal living area which includes a fireplace, painting studio, second-floor en-suite bedroom and access to the outdoor spa. Off the main staircase and upstairs, the master suite encompasses the entire south-eastern wing of the house and includes vaulted ceiling master bedroom with a fireplace and French doors that step out to the south facing deck with dramatic views of Mecox Bay and the ocean beyond. There is a large, fully marbled master bathroom with radiant heat floors and views of the farm fields. Two large walk-in closets complete the master domain. There are three additional ensuite bedrooms, all with vaulted ceilings, closets with custom built-ins and fully marbled spa-like bathrooms. The Tower study with a fireplace and dramatic water views completes this floor. The level of excellence continues outside to the design of the six acres of gardens and accessory structures including carriage house, heated gunite pool within the alle of Sycamore trees, vast rose garden, orchard of 60-year-old apple trees, portages, flower cutting gardens, dry stacked stone walls, and gravel walkways, specimen mature trees and plantings all laid out in the classic English garden style design, with room for a tennis court. A beautiful nature path leads down to the waterside with a large dock, perfect for motor boats and kayaks.
