About this home
Refined Craftsman rambler in the sought-after gated community of the Ridge at Sawyer Lake, perfectly sited on a half acre backing to 175 acres of protected HOA greenbelt for exceptional privacy. The great room is the heart of the home, showcasing 9'+ ceilings, a natural gas fireplace, and an effortless flow designed for both elevated entertaining and comfortable daily living. The adjacent chef’s kitchen is equally impressive, featuring an expansive island, farmhouse sink, double wall ovens, stainless steel appliances, and a generous eat-in area. The main level also offers a formal dining room, private office, well-appointed secondary bedrooms and baths, and a spacious utility room. The serene primary suite serves as a luxurious retreat with a lux five-piece bath, expansive walk-in closet, and French doors opening to a private covered patio. A versatile bonus suite above the garage with a 3/4 bath is ideal for guests, media, or a secondary office. The oversized three-car garage with dedicated work and storage areas, expansive driveway with ample parking, and RV parking pad provide exceptional functionality. Covered rear outdoor living spaces extend into the fully fenced grounds, enhanced by mature landscaping. Fresh interior and exterior paint complete this polished, move-in ready residence.
