Sagaponack. A very private 2.1 acre flag lot is the setting for this sensational modern residence offered pre-construction by a collaboration between the internationally acclaimed firm Resolution:4 Architecture and master builders Reinhardt/O'Brien. Overlooking preserved land this 6 bedroom 7.5 bath totals aprox 6500 sq ft. Walls of glass envelope the home creating a panoramic synergy between the sublime interiors and the 2-acre expanse of nature. Kitchen, dining and living room all open up to the outdoors. A ground floor master suite with a striking bath has an adjacent library/office. Upstairs there is a rooftop master suite and 4 additional en-suite guest bedrooms. The second floor den and green roof living pavilion with fireplace and Jacuzzi tub provide a multi-season entertaining space with 360-degree views of the landscape. Potential for an addititional fully finished lower level would add 2 guest bedrooms and full bath, gym, media room and wine storage. Outside, a 12 x 50 heated Gunite pool with ample lounging area is offset by an architectural fire-pit punctuating the landscape. An incredible value opportunity in Sagaponack, America's second most expensive zip code and an ideal central Hamptons location only minutes to Wainscott's Beach Lane and Sagg Main ocean beaches and world class shopping and restaurants in Bridgehampton, Sag Harbor and East Hampton.
