Welcome to 16 Middlebrook Lane, a stunning custom-built Colonial in one of Wilton's most desirable cul-de-sac neighborhoods. Set on more than four park-like acres and surrounded by conservation land, this exceptional home offers elegance, craftsmanship, privacy, and comfort. A dramatic main hall creates an immediate sense of arrival with a sweeping staircase and refined architectural details. The chef's kitchen features two large islands, honed marble countertops, high-end appliances, generous storage, and French doors to the rear patio. The kitchen opens to an inviting dining and living area with a wood-burning fireplace, while the formal dining room offers coffered ceilings and an adjoining butler's pantry/bar. Oversized windows fill the formal living room with natural light, complemented by a fireplace and bar, and flowing into a custom office with built-ins and its own fireplace. Upstairs, the extraordinary primary suite lives like a private residence with a sitting room, coffee bar, private balcony, generous walk-in closets, and spa-like bath with soaking tub and steam shower. A private staircase leads to the third floor with half bath, ideal for an office, studio, or retreat. Four additional en-suite bedrooms, laundry, and a bonus room complete the second floor. The finished lower level offers recreation space, gym, game room, and full bath. An elevator serving all four levels adds rare ease and flexibility.
