It's rare to find a home where every space has been thoughtfully designed to make everyday living feel effortless. Built in 2021, this custom Colonial pairs an exceptional floor plan with a backyard that rivals a private resort. At the center of the home, the expansive eat-in kitchen is designed to bring everyone together. An oversized center island, high-end appliances, walk-in pantry and abundant workspace flow seamlessly into the dining area and fireplaced family room, creating an open, inviting space for everything from busy weekday mornings to holiday celebrations. Formal living and dining rooms offer additional gathering spaces, while a private first-floor office and adjacent full bath provide flexibility for working from home, overnight guests or multigenerational living. Upstairs, the primary suite is a true retreat, featuring a spacious bedroom, walk-in closet, beautifully appointed bath and an adjoining bonus room that easily adapts as a sitting room, fitness space, nursery or second home office. Three additional bedrooms, each with direct access to a full bathroom, offer comfort and privacy for family and guests alike. A second-floor laundry room adds everyday convenience exactly where it's needed. Step outside and discover what truly sets this property apart. The backyard has been designed as a private destination, complete with a heated in-ground pool, expansive patio, composite deck, hot tub and sauna—spaces that invite both quiet relaxation and effortless entertaining throughout the seasons. Whether hosting summer gatherings or enjoying an evening under the stars, this outdoor retreat feels more like a luxury resort than a backyard. The unfinished basement offers nearly 1,500 square feet with high ceilings, providing outstanding potential for future living space, recreation or hobbies as your needs evolve. Located in the award-winning Acton-Boxborough School District and convenient to conservation trails, shopping, commuter routes and the South Acton commuter rail, this home offers the rare combination of modern construction, exceptional craftsmanship and a lifestyle that is difficult to replicate. Here, luxury isn't defined by a single feature—it's found in the way every space works together to make daily life
