Introducing Maritime Haven, a brand-new waterfront neighborhood of just seven homesites on Buzzards Bay, offered to the market for the very first time. Now available: Lot 49, known as 1 Haven Court. This lot is 1 acre, offers stunning views of Buzzards Bay and deeded sandy beach access, and is ready for the coastal home you have been waiting to build. This lot is approved, cleared and shovel ready, so you can skip the guesswork and go straight to design. Utilities will be in place, including town water, town sewer, natural gas and 400-amp electrical service, a rare combination for a coastal lot. Set on a quiet new court on Sias Point, the homesite has the feel of a classic New England seaside neighborhood, with room for a generous home, a pool, a wraparound deck, gardens and outdoor living. The location is a big part of the draw. Sias Point sits between the Cape Cod Canal and Onset’s outer harbor, minutes from the Canal bike path, Onset Village’s beaches, restaurants and summer concerts, local marinas and some of the best boating on the South Coast. You are just before the bridges, so you can enjoy the Cape lifestyle without the bridge traffic, with easy access to Routes 25, 195 and 495 and roughly an hour to Boston or Providence. Lot 49 is one of only seven homesites in the neighborhood and is the first to be released. Please inquire about additional lot availability and pricing. Build with confidence: bring your own builder, or contact us and we will connect you with trusted local builders who know coastal construction and can help bring your vision to life. Maritime Haven: your place on Buzzards Bay.
