About this home

Set amidst the natural beauty of New Castle, this is a rare offering that captures the essence of refined coastal living. Boasting beautiful views of Little Harbor’s back channel, and Sagamore Creek, this elegant 3+ bedroom, 3.5-bath condominium offers over 3,400 square feet of light-filled living space in a private setting surrounded by mature woodlands and abundant wildlife. Designed for both elegance and easy single-floor living, the home features a sought-after first-floor primary suite with newly finished walk-in shower and huge soaker tub, radiant flooring, elevator access, and expansive windows that fill the home with natural sunlight. The chef’s kitchen is appointed with granite countertops and Wolf appliances, while the large patio and deck spaces provide lots of opportunities to connect with the peaceful landscape and water views. There are two additional bedrooms and full bath located on the second floor, while the lower floor offers an additional bedroom space, full bath, and a sun room with incredible harbor views. Additional highlights include a climate controlled underground garage with several dedicated storage rooms, and very low New Castle property taxes. Available for the first time in over 20 years, this stately home offers a combination of privacy, outdoor space, luxury finishes, and captivating coastal scenery, not found in many homes on the Seacoast. Walk to the outdoor heated pool, tennis courts, and the Wentworth Hotel & Spa. The marina and golf course are located right next door!
