Welcome to Notre Colline Estate, a private 56+ acre country estate surrounded by rolling meadows, gardens, ponds, and Catskill Mountain views. French for ''Our Hill,'' Notre Colline has an easy sense of belonging to its landscape. Designed for comfort, entertaining, and longevity, the Greek Revival architecture-inspired residence spans three finished levels with energy-efficient radiant heated floors, a metal roof, and a fully integrated smart home system. Light-filled gathering spaces center around a chef's kitchen with French doors that open to a stone patio, outdoor kitchen, and landscaped grounds. The primary suite features a gas fireplace and a spa bath, and the finished lower level adds a recreation room, sauna, and full bath. Outdoors, a peaceful pond with a footbridge, raised-bed gardens, and a new insulated outbuilding complete this serene retreat, just minutes from Chatham Village.
