Boasting nearly 5,000 finished square feet, a 4-car oversized garage and an open floor plan, this home offers luxury, serenity, and ample space for both entertaining and daily living. -----

Step inside to discover soaring 11-foot ceilings and beautiful hardwood floors throughout much of the main level. The expansive great room, featuring a gas fireplace, opens to a massive 56’ x 14’ deck that overlooks the private backyard. Adjacent to the great room is a formal living room and dining room, ideal for hosting guests. The gourmet kitchen impresses with rich hickory cabinets, granite countertops, a double oven, pantry, stainless steel appliances, and a spacious bay-window breakfast area.

Private deck access from the primary suite leads directly to the relaxing two-year-old hot tub or a place to sit & enjoy the birdsong & your morning coffee. A thoughtful split-bedroom design offers two additional generously sized main-level bedrooms each with their own full baths, and a bright office / den with a bay window and peaceful wooded view. -----
