A rare offering in the coveted Marina Heights enclave of Wentworth by the Sea. This 4,200+ SF, 4-bedroom (+office), 6-bath residence features an expansive main level with 10-foot ceilings and floor-to-ceiling windows that frame breathtaking views of the Marina and the Atlantic Ocean, and maximize the southern exposure making the living spaces light and bright. A dramatic two-story foyer welcomes you into a sun-drenched living room, which seamlessly flows into a chef-friendly kitchen anchored by a long peninsula island for gathering. The kitchen is open to the family room that features a wood-burning fireplace. Step out onto the oversized deck—the ultimate vantage point for coastal entertaining. Functionality meets style with a dedicated mudroom and separate laundry room off the attached garage, and a large pantry off the kitchen. For intimate gatherings, the dining room has a cozy, tavern inspired feel with custom built-ins, and can easily accommodate many dinner guests. Widely considered the premier floor plan in the neighborhood, the main level offers *almost* one-floor living, with the luxurious primary suite just two steps up from the living areas. It includes direct deck access, a sprawling walk-in closet, and a spa-like bath with an oversized walk-in shower, soaking tub, and a water closet with a bidet. Upstairs provides three additional bedrooms (two en suite), plus an office, an additional 3/4 bathroom, and a cedar closet. The walk-out lower level features a 6-seat wet bar, billiards area and a climate-controlled wine cellar, a dedicated space potential for a home gym and potting shed, all while maintaining direct outdoor access and ocean views. The atatched 3-car garage and exclusive access to the association pool, tennis courts, beach, and marina will seal the deal. New Castle taxes are famously low. Very walkable, bike-friendly, just minutes from downtown Portsmouth, beaches, boating, restaurants and more. Residents are prioritized for marina boat slips.
