Spectacular views, light and privacy from this island property. Expand the current home or build your dream home on this .57-acre parcel with 300' frontage on the Piscataqua River offering a rare deep-water access (dock in need of repair/replace) and mooring. Endless potential with elevation to support new construction not limited by flood zone requirements. The current 1 bed, 1 bath, 1200 SF bow roof cape plus heated 107 +/- SF boat house is privately situated on Goat Island with water views from every room. Watch the working waterfront of huge ships and barges traveling in and out of the harbor, submarines coming and going for service, fishing boats, sailboats, yachts, the Tall Ships, aquatic and marine wildlife - there is always something to watch. Surrounded by the Piscataqua river, view the Wentworth by the Sea hotel to the south and marvel at the lights and sounds of the Portsmouth Naval Shipyard including the National Anthem in the morning and Taps at days end to the north. Whether you expand the existing home or start anew, this captivating location will steal your heart.
