At just one year old, this exceptional Clayton residence pairs timeless architecture with the scale, finish, and infrastructure of sophisticated new construction. A three-stop elevator serves all levels, while a main-floor primary suite establishes a highly desirable floor plan rarely found in newer Clayton homes. Generous living and entertaining spaces are complemented by a four-car tandem garage and an extensive collection of custom upgrades completed beyond the home’s original construction. The main level is anchored by beautifully proportioned living spaces and a refined kitchen designed with custom cabinetry, premium appliances, and elevated finishes. The primary suite offers a private retreat with heated bathroom floors, a steam shower, custom closet, and soaking tub. A dedicated office with custom built-ins, main-floor laundry, and thoughtfully integrated technology further distinguish the residence. Upstairs, three private bedroom suites are each finished to a notably high standard, with individually appointed baths featuring custom vanities along with professionally designed custom closets. A flexible additional living space provides an ideal setting for a study, lounge, homework room, or secondary office, while a second laundry room adds convenience to the bedroom level. The finished lower level extends the home with an additional bedroom and full bath, expansive recreation and entertaining space, and a wet bar. Additional investments include a Crestron system, Lutron shades, upgraded wool carpeting, epoxy garage flooring, fencing, complete landscape redesign, enhanced lighting, and custom office millwork. With a four-car tandem garage, five private bedrooms across three finished levels, elevator access throughout, and a substantial program of owner-added improvements, this nearly new residence presents a compelling opportunity to acquire a highly finished Clayton home without the timeline, uncertainty, or additional investment associated with building and completing one from the ground up.
