About this home

Welcome to Stonington Borough's Premier Luxury Waterfront Property. Located on Stonington Harbor the residence has breathtaking views that connect one directly to the water. Originally built in 1870 the house was completely taken down and rebuilt with close attention to custom design and technology to offer state-of-the-art living spaces. This stunning 4 bedroom, 5.5 bath home (all bedrooms have ensuite baths) is designed to feel like you are on a contemporary, luxury yacht. The open floor plan encompasses all 3 living levels. A NanaWall transitions the inside main living area to the outdoor extra large IPE deck beautifully and transparently. The chef's kitchen is equipped with professional grade appliances. The master suite deck is a private oasis overlooking Long Island Sound. Some of the details that make this property truly magnificent are: electrochromic smart glass bathroom windows for privacy; elevator; waterfall feature in professionally landscaped back yard with irrigation system; private dock; whole house generator; Tesla charging station: one car attached heated garage; hurricane impact windows & doors; FEMA approved 100 year flood de-watering system; off street parking for up to 6 cars. Furniture will convey. This amazing property is a joy to show, please watch video, qualified buyers only.
