Overlooking the fairways of Mount Vernon Country Club, this beautifully updated colonial offers a rare combination of refined interiors, generous scale, and an exceptional setting. Set on a private .53-acre lot with sweeping views across the club's 128 acres (most notably Hole 8, the straightest green on the front nine and a Par 4 gateway view toward the clubhouse), this is Mount Vernon living at its best. Originally built in 1980 and thoughtfully renovated and expanded in 2011, the home spans approximately 4,880 finished square feet across three levels. Improvements include a 400-square-foot sunroom, an opened and refreshed kitchen, and a lower-level addition currently used as a gym (formerly a photography and framing studio). Owned by a former professional organizer, the home is impeccably maintained and intuitively designed. Quite simply, you've never seen a house this perfect. The main level is designed for both everyday comfort and effortless entertaining, featuring formal living and dining rooms, a private office with custom built-ins, and a spacious family room with a wood-burning fireplace. The family room flows seamlessly into the sunroom and kitchen, where abundant natural light and direct access to two expansive and connected Trex decks (one covered and outfitted with ceiling fans) create a seamless indoor-outdoor connection overlooking the golf course. The refreshed kitchen features replaced quartz countertops, a new refrigerator and dishwasher, and an updated faucet, offering clean lines and modern functionality. Tucked just behind the kitchen is a scullery with a sink, desk space, and exceptional storage, perfect for hiding small appliances and keeping the main kitchen effortlessly polished. Plantation shutters throughout enhance both privacy and architectural character. Upstairs, four large bedrooms include a generous primary suite with multiple walk-in closets and an all-marble en-suite bath. Secondary bedrooms feature charming dormers with built-in desk areas, ideal for homework or work-from-home flexibility. New carpeting, an updated hall bath, and a large linen closet complete the upper level. The walk-out lower level adds outstanding versatility with a recreation room, den, full bath, hobby room, and a dedicated exercise room with gym flooring. The gym addition can easily be converted into a legal fifth bedroom or in-law suite, offering excellent future flexibility. Since 2020, the owners have invested approximately $115,000 in improvements, including full interior repainting, added crown molding, refinished stairs with a wool runner, updated door hardware, a new HVAC system, new gutters, a 42-inch Dacor refrigerator (2025), added insulation for energy efficiency, a laundry room remodel, and a new front door. Additional highlights include an oversized two-car garage, main-level laundry and mudroom, all windows replaced with Renewal by Andersen (2014), a storage shed, and abundant storage throughout with two pull-down attic spaces. With privacy, usable and fully fenced outdoor space, and unobstructed golf course views, this exceptional home presents a rare opportunity in a sought-after Mount Vernon setting, elegant, organized, and effortlessly livable.
