Set on 1.35 acres+/-, this newly constructed Southampton residence by M & M Custom Homes spans approximately 10,000 SF+/- with 8 bedrooms, 7 full and 2 half baths across three finished levels, along with an elevator, two-car garage, heated Gunite pool and spa, and all-weather tennis court. Designed by architect Michael Dunn, it is the second in a collection of three new homes taking shape in this intimate setting. Expansive interiors, contemporary architecture, and a strong connection to the outdoors shape the home throughout. The first floor is organized around a dramatic double-height foyer that opens directly into an equally soaring family room with fireplace, giving the main level an immediate sense of openness and scale. A formal dining room sits just off the foyer, while beyond the family room, the plan opens into a generous kitchen and expansive living and dining area across the rear. The kitchen is equipped with Wolf and Sub-Zero appliances, a substantial center island, and separate pantry, with a second fireplace anchoring the main living space. Covered porches extend the interiors outdoors from multiple points, while a private bedroom suite with a walk-in closet and full bath is set apart from the principal gathering areas. The second floor is centered around a spacious primary suite with two walk-in closets, a large bath, and a private balcony. Four additional bedrooms occupy the opposite side of the floor, each with a walk-in closet and private bath, while a dedicated laundry room adds convenience. Double-height openings above the foyer and family room bring architectural interest to the upper level and maintain a connection to the spaces below. More than 3,000 square feet of finished space on the lower level significantly expands the home's living area. A large lounge forms the center of the floor, joined by a media room, wine cellar, workout area, and a second laundry room. Two additional bedrooms and a full bath are located separately at one end of the level, creating useful accommodations for guests. The elevator continues to this floor, providing direct access throughout the entire home.
