Conceived by award-winning architect Joseph Eisner, AIA, LEED AP, and newly completed to perfection, this modern masterpiece is the latest creation of a preeminent home design aficionado, featured in prominent publications and sought-after by the most discerning. Nestled in a quiet, coveted cul-de-sac, 20 Cove Neck Lane boasts an incomparable location, resting moments from beautiful Fish Cove, minutes to Southampton Village, North Sea Harbor, Peconic Bay and pristine ocean beaches, as well as the Southampton Youth Services Fitness Center and Tennis Club. Set on a lush .84 acres of elevated grounds, the exquisite 4 bedroom 4.5 bathroom gem abuts 10 acres of reserve land for the ultimate peace and privacy. An expansive 4375 square feet of luxurious living space is met by serene and stunning outdoor environs that afford a perfect backdrop for entertaining. Lounge and dine alfresco on the generous wood deck with a built-in grill and fridge, or enjoy summer swims in the sparkling in-ground pool. Refined interiors are light, bright and spacious, offering gorgeous views of greenery and an open-concept layout for the host. The wonderful great room with wide-plank wood floors and a sleek wood-burning fireplace is complemented by a lovely dining alcove enveloped by windows. The brand new state-of-the-art kitchen is tailored to the chef, styled in white with abundant cabinetry, stone countertops, and a large island with extra seating. A sky-lit sunroom with a ceiling fan and tile flooring extends the kitchen/party area, offering huge sliding glass doors leading to the pool and outdoor oasis. Among the additional highlights are primary suites on 2 levels (one accessing the deck and pool), 3 additional guest rooms, all new high-end spa baths, a newly-added finished lower level, full laundry room with storage, refreshing outdoor shower, and oversized detached 2-car garage. Every detail of this exceptional upscale home has been thoughtfully considered for optimal aesthetics, functionality, and sustainability. Topping the allure is the premier address, in close proximity to all the attractions of Southampton, Bridgehampton, Sag Harbor and Water Mill, and an easy commute to Manhattan!
