29 Harding Terrace offers 270-degree unobstructed views of Sag Harbor's main waterway and 500 acres of protected marshland reserve--and all the gorgeous birds and amazing fauna that live there. This 2,500 square feet custom-built home, constructed in 2001, has 4 bedrooms and 3 full baths. One ensuite bedroom is on the ground floor as well as two more guest bedrooms with a shared bath. All bedrooms have cork flooring. A laundry room and workroom, as well as a boat storage/small car garage, complete the first floor. The double-wide staircase up to the second level, lined with a wall of glass framing stunning images of the reserve, leads to jaw-dropping views. The living room with a fireplace and attractive kitchen has radiant-heated bamboo floors. The master bedroom suite has a picture-perfect framed view of the reserve facing east. There is a wrap-around deck that affords cool breezes off the harbor and stunning sunrise and sunset ring-side seats. There is a creek that runs from the harbor to the reserve which has been earmarked to be dredged to more elegantly and efficiently feed the marshland. 29 Harding Terrace has steps down to its own private sand beach where you can grab a kayak and spend some quality time on the water. The property extends under the creek up to the high-water mark on the sand bar to the Harbor and comes with deeded mooring rights. Private. Wide-open views of the harbor with all its poetry-in-motion created by the boats and water activities, and the reserve, and only one adjacent neighbor ever. It really doesn't get any better. But wait! Applications are pending for a 15x24 feet extension off the waterside of the house, featuring a great room or a ground-floor master suite with a 4 feet deep heated swimming pool on top, just steps off the living room. So from your fireside seat you could look over the pool to the harbor and reserve. Water, water, water. This future project would be incredible, but as it is, 29 Harding Terrace is a show-stopper--fresh sea air, sunrises and sunsets, privacy, amazing views, and room to breathe, play, relax, enjoy.
