Introducing Garden Cottage, a private gem on the quaint island of New Castle. This Victorian-inspired, shingle-style residence is sited on a bluff overlooking Little Harbor and the Piscataqua River, with spectacular sunset views. Casual elegance is defined throughout the home with its floor plan, craftsmanship and décor. A custom kitchen with oversized windows (and incredible views) opens to a cozy living room with gas fireplace. French doors offer a seamless transition from the dining and breakfast rooms to an impressive 33' conservatory with heated Fioranese tiled floors overlooking manicured lawns and gardens. The second floor primary suite offers a luxurious bath and walk-in closet (and more magnificent views). From there, a staircase leads to a unique third floor tower room, the Poet's Tower, with panoramic Seacoast vistas. Guests may not want to leave their suite located in a separate wing with its own entrance (note: accessory dwelling potential). Enjoy outside entertaining on a wonderful bluestone patio, complete with a gas fire pit, unique built-in granite "book" shelf and stone fountain. Garden Cottage offers a sense of tranquility, yet is close to the center of town, beaches, Great Island Common and Wentworth by the Sea Hotel, Spa, Marina and Country Club…and vibrant, historic Portsmouth is just over the bridge!
