Description

Exceptional, Fully Renovated Colonial in Serene Park-Like Setting. This spectacular 4 Bedroom Custom Colonial was completely renovated and expanded, and meticulously appointed with luxurious custom finishes including hand-hewn beams, reclaimed wide-plank hickory wood flooring, and beautiful stone work. A semi-open floor plan features generously sized rooms bathed in warm natural light, high ceilings and top-of-the-line appliances. The hub of the home is a show-stopping kitchen with all the bells and whistles: custom cabinetry, two large islands, hickory baker's table, dining area overlooking the pool and yard, separate walk-in pantry, sitting area with fireplace, full-size SubZero refrigerator and freezer, and SO MUCH MORE! The second level features a private primary suite with an office, 2 walk-in closets and stunning marble primary bath with radiant heat. Walk-out lower level with second kitchen, full bath, rec room, gym and more. Situated on just over 3 acres and backing up to preserved park land, this home offers a restful retreat with great outdoor space: expansive stone patios, heated salt-water pool and hot tub with waterfall, outdoor gas BBQ, fire pit, gardens and great views. See feature sheet for additional details. A true show-stopper!
