About This Home
Brand new sleek build by KB Building LLC is completed and ready for a new owner. This exquisite modern residence in prime Water Mill is nestled on nearly 5 acres on a cul-de-sac with bay views, pool & spa, pool house, outdoor kitchen with heated dining and tennis. The thoughtfully designed 9 bedroom, 10 full baths, 2 half baths with a home spanning 10,750 square feet on 3 levels has been masterfully crafted with superior douglas fir and steel girder construction and is brimming with premium-quality materials from top to bottom. A gorgeous modern stucco and wood exterior and pristine landscaping optimize curb appeal. Walls of glass and aluminum European tilt-and-turn windows invite in brilliant natural light and showcase water view vistas and amazing sunsets. The private backyard oasis is exceptional, featuring a sparkling 20x50 heated gunite saltwater pool with sundeck and spa surrounded by stay-cool patios for lounging and entertaining. Superior-grade exotic Brazilian garapa decking with glass railings provides further outdoor enjoyment and peaceful views. Interiors are meticulously finished throughout with the highest-end elements, from solid custom interior doors to rich 7-inch-wide white oak flooring, 2 chic fireplaces, marble and porcelain baths, top-of-the-line plumbing fixtures, state-of-the-art lighting with LED recessed lights on ceilings and walls, and a contemporary floating oak staircase with LED lights and glass railings enveloped by 2-story glass walls. The airy double-height living room is anchored by an elevated gas fireplace wrapped in stone and flanked by horizontal boards. Imported European custom cabinetry, a 10-foot center island clad in Calcutta Quartz, and a suite of professional appliances set the tone for the chef as well as an additional working kitchen behind the main kitchen for extra prep work. This beautiful house also features primary bedroom suites on the first and second floors, as well as a rear staircase that leads to a private space, ideal for a private guest suite, home office, or studio. The second floor primary has its own private deck to view the water and sunsets. Comfort continues on the finished lower level with 10-foot ceilings, a theater, a gym, infrared sauna and lighted wine storage. Other highlights are a 3-car garage with frameless glass doors, central vacuum, 6-zone HVAC, solar panels, and propane gas heating. All of this in an outstanding location just minutes to Southampton Village and the ocean!
