    Updated to perfection, this classic 5-bedroom Connecticut Colonial offers over 5,500 square feet of curated living space, harmoniously positioned on a private, sought-after cul-de-sac within an enclave of 4+ acre estates. The residence unfolds with a sun-drenched brand new chef's kitchen featuring custom cabinetry, premium quartz countertops, and high-end appliances, all flowing through floor-to-ceiling glass sliders to an expansive deck and a grand family room anchored by a stately fireplace. A sophisticated main level offers a formal dining room, elegant living room, and a bespoke private office with picturesque views of the park-like grounds. Upstairs, the primary suite serves as a sanctuary with a dedicated sitting room and new spa-inspired bath, while a separate private-entry in-law suite provides a secluded fifth bedroom and sitting area for ultimate versatility. The newly finished 1,700-square-foot walk-out lower level elevates entertaining with a massive media/playroom, an additional family room, and potential for a custom wine cellar-all just minutes from the vibrant New Canaan town center, top-tier schools, and the Metro-North train.
