This 5-bedroom, 4-bath masterpiece offers over 4,000 square feet of thoughtfully designed living. Masterfully designed by architect JV DeSousa, the home is defined by clean lines, abundant natural light, soaring ceilings and a sense of volume and ease throughout. The open-concept main level is both refined and highly livable, anchored by custom artistic elements by local artist Osbourne Sculpture, including a statement fireplace, sculptural railing, and bespoke kitchen island. The flexible layout offers true versatility, featuring a spacious main-level office that easily converts to a guest suite with a built-in Murphy bed and access to an ensuite full bath. Function is seamlessly integrated with walk-in closets, built-in dressers, generous shelving, and a well-appointed laundry/mudroom with utility sink and custom cubbies. An oversized garage adds storage and convenience, while recent system upgrades, including two new furnaces, A/C systems, and solar panels producing energy beyond current usage, enhance efficiency and long-term value. Thoughtful capital improvements have been made throughout, including an extension of the outdoor living experience with a composite deck, wood fencing, a premium pergola, and low-water landscaping creating a private, low-maintenance setting designed for both relaxation and entertaining. The fully finished lower level expands the living space with a versatile layout, complete with built-in Murphy bunk beds, ideal for guests, media, or play. Fresh, intentionally minimal and architecturally distinct, this home offers a refined backdrop and a rare opportunity to own a truly enduring piece of North Boulder.
