Experience 'Lighwater' and its remarkable sense of serenity. Upon arrival one is immediately enveloped by the exquisite, mature setting the owners, landscaping visionaries, have cultivated since 1985. With a wide array of flowers, bushes, water features, bridges, walking paths, a meditation garden, and stunning water views, the 3.73-acre property consists of two distinct buildings that blend seamlessly with the natural surroundings. The home draws inspiration from architect Frank Lloyd Wright and embodies the Art & Crafts home style. It boasts 110 feet of waterfront access and multiple parking areas. The home spans over 2,900 square feet and is characterized by horizontal lines, open floor plans, beautiful Asian-inspired glass windows, and seamless indoor and outdoor space integration. A generous foyer, an eat-in kitchen with a center island, a spacious dining room, a wide-open living room with a two-story ceiling, mezzanine, and a wonderful wood-burning fireplace are featured. Beyond the living room is a wrap-around heated sunroom with marvelous views and access to the stone patio and river-side gardens. The first floor includes an in-home office and/or hobby/sewing room, a laundry room, and a full bath. Upstairs are two primary bedroom options, both sharing a tiled full bath. Additionally, there is a spacious flex room with a private staircase from the foyer. The property includes a significant carriage building, suitable for an on-site business, that offers finished open space with lovely views of the river and woods along with a large two-car garage below. The unfinished basement in the main house contains a utility area. Some updates to the property include a wall-hung hot water furnace, a septic system, a newer roof, and fully mature landscaping.
