Welcome to this exceptional luxury residence where thoughtful design, high-end upgrades, and modern convenience converge to create an unparalleled living experience that only completed construction barely 3 years ago. Featuring 4 bedrooms, 3.5 baths, and a spacious 3-car garage, this fully finished walkout home is truly better than new—offering enhancements and amenities rarely found in builder-grade construction. From the moment you enter, you’ll appreciate the elevated architectural details including arched doorways, soaring ceilings, and a breathtaking floor-to-ceiling, two-story stone fireplace that anchors the open-concept main living space. A private, enclosed office with elegant French doors provides the perfect work-from-home environment, while a versatile flex space off the kitchen and dining area offers endless possibilities—ideal as a sitting room, coffee or wine bar, play area, or secondary office. The gourmet kitchen is designed to impress and built for entertaining, featuring premium stainless steel appliances, built-in ovens, a 5-burner gas cooktop, and an oversized island with abundant storage and seating for up to four. Custom cabinetry includes soft-close doors and drawers, pull-out shelving, a built-in silverware organizer, under-cabinet lighting, and expansive pantry storage. Integrated Bluetooth surround sound enhances the atmosphere for cooking, dining, or hosting guests. Every surface reflects quality, with all countertops upgraded to quartz or granite—no builder-grade finishes here. The home is equipped with a whole-house media tube running from attic to basement, built-in 5-speaker surround sound, Bluetooth-enabled speakers in both the kitchen and covered deck, and WiFi repeaters on every level for seamless connectivity. Retreat to the luxurious primary suite, where a spa-inspired bathroom features an oversized custom-tiled shower with dual shower heads and jetted sprays. Upstairs laundry adds everyday convenience, located near all bedrooms. The fully finished walkout basement expands your living space with a large family room, full bath, kitchenette, and private sleeping area—ideal for guests, extended family, or multi-generational living. Built with a 9-foot pour, the lower level feels open and inviting with direct access to the backyard. Step outside to a fully covered composite deck overlooking a serene, private setting backing to woods and a natural stream. The adjacent ravine and common ground ensure no future development, offering unmatched privacy and a uniquely expansive lot. A lower-level patio provides additional space for entertaining or relaxing. The exterior is equally impressive with irrigation, ample custom lighting, and an invisible dog fence. Inside, enjoy premium finishes such as real wood blinds, motorized remote-control shades, custom built-in shelving with dimmable LED lighting, and a smart thermostat. The garage is a standout feature—fully finished, insulated, and heated, with custom lighting, quiet wall-mounted WiFi-enabled garage door openers with battery backup, and a dedicated EV charging circuit already installed. Additional features include a built-in, active radon mitigation system and a comprehensive alarm system with integrated doorbell camera for peace of mind. Why wait to build when this meticulously upgraded, move-in-ready home offers it all? Combining luxury, functionality, and an unbeatable private setting, this turn-key home is a rare opportunity you won’t want to miss.
