Design meets function in this newly constructed custom 5000 square feet green home, which is both an entertaining showpiece and a modern marvel of captivating living. On a 60 plus acre preserve, this eco-friendly home is set between the ocean beaches of Sagaponack and the charming village of Sag Harbor. This loft-like gem features a huge, 1930 square feet master suite, 3 additional oversized en-suite bedrooms, 2 half baths, a gas fireplace, open chef's kitchen with a butler's pantry, double-height living and dining area with a dramatic 16' by 16' wall of glass and an oversized garage. The yard features professionally landscaped gardens, a 42' heated gunite pool, an exterior built-in grill area, and a bluestone fire pit. Each of the first-floor bedrooms offers private retreats off of the main living area and open to their own private decks. A dramatic floating Brazilian walnut staircase leads upstairs to a home theater with built-in 7.1 surround sound and a wet bar, a home office, a powder room, and the two master bedrooms. The dual masters each are equipped with spa-inspired, 5 fixture bathrooms, dual vanities, radiant heat floors, and oversized soaking tubs. The expansive master suite features double-height ceilings, custom closets galore, and a private mahogany deck overlooking the pool, terraced gardens, and acres of adjoining preserve. The landscaped acre parcel offers serene privacy as it backs up to over 60 acres of Peconic Land Trust preserve! The Land Trust also owns the lots on either side.
