Walls of glass capture enduring Lieutenant River and Nature Conservancy views, an ever-changing seasonal pallet at Marshlands. Nautilus Architects created this spectacular design beginning with the atrium entry illuminating the surrounding rooms. The public rooms flow seamlessly to stunning decks. Top end appointments include architectural surfaces of honed concrete, stainless steel, custom lighting and millwork. Enjoy an exceptional chef's kitchen equipped with a Blue Star cooktop and centerpiece blackened steel vent hood, Wolf steam oven, Subzero and a butler's pantry with ancillary cooling and freezer. The great room and dining room meld seamlessly to the living room with repetitive use of honed concrete as the fireplace focal point. The main level primary bedroom suite sits privately at the home's south end. Find a spa bath, generous closets, large office and private laundry. A central turned stair leads to a central gathering space, three lower-level bedrooms and two full baths. Walls of glass echo the views and doors to the deck afford guests a private retreat. Outside, a screened porch overlooks the heated gunite pool with teak surround and the river below. Kayak from the water's edge. Fit and finish extend to top end mechanicals: 5-zone Viessman heating and a whole house, on demand, generator. There is exceptional storage. High above the waterline, fully fenced and tucked into private Longacre, it's just a mile to the village, 3 miles to Saybrook Station. Serenity.
