This custom Southampton home features 7 bedrooms, 6.5 bathrooms, and was expertly constructed just a few short years ago, and then substantially upgraded throughout by an industry-leading designer. The entry greats you with abundant natural light and a gallery of excellent storage. The space flows to a custom chef's kitchen with a stunning island featuring waterfall stone and expansive seating. This flows into an open great room centered around a fireplace. The first floor also offers a mud room side entrance, formal dining room and a junior primary with en-suite bathroom. On the upper level you will find a primary suite with outdoor terrace and a spacious spa inspired bathroom, including soaking tub and glass shower. There are three additional upper-level guest bedrooms, all with en-suite bathrooms and generous closets, all adjacent to the second story laundry room. In addition to the four bedrooms, there is an incredible bonus room on the upper-level that also features a full bathroom and is the perfect space for a play room, additional media, or a great place for sleep overs! The lower level was completely re-imagined by the current owners and upgraded with a beautiful media room, wet bar, gym, and two additional bedrooms. This .7 acre flag lot features an expansive driveway, heated gunite pool, and attached 2-car garage. A dedicated dock slip accessible through the rear yard gate. The dock slip accommodates a 30 +- Foot boat. All this a quick stroll to a Bay beach, and just minutes to shopping, dining, and world-renowned beaches. An opportunity not to be missed!
