About this home

Welcome to The Roaring Brook Estate, a rare Chappaqua retreat set on more than seven private acres of natural beauty, architectural significance, and quiet history. Just about one hour north of Manhattan, this distinctive property offers a remarkable combination of privacy, land, design, and lifestyle. Originally built in 1958, the residence is known in architectural records as the Donald Miller Jr. House, Now the Roaring Brook Estate, and was designed by celebrated American modernist architect Edward Larrabee Barnes. The home was featured in Architectural Record Houses of 1959, with USModernist identifying the original project team as including structural engineer William Atlas, builder O’Brien and Kinkle, landscape designers Bye and Herrmann, and interiors by Mary Barnes and Emily Malino. The architecture reflects Barnes’s modernist philosophy: clean lines, openness, natural light, and a close relationship between the residence and the surrounding landscape. Glass, structure, and proportion work together to frame the outdoors rather than compete with it, creating a home that feels deeply connected to its setting. Surrounded by mature trees, open lawns, a peaceful brook, and beautiful natural scenery, the estate creates an immediate sense of calm and escape. The property unfolds through light, landscape, and privacy — morning sun through the trees, quiet afternoons across the grounds, and peaceful evenings surrounded by nature. Here, the land is not simply a backdrop; it is part of the living experience. In addition to the main residence, the property also includes a separate guest house featuring a beautiful studio space, currently occupied by a tenant. This added structure enhances the estate’s flexibility and creates potential for guest accommodations, creative use, private work space, or income-producing use, subject to applicable lease terms and local requirements. This is a unique opportunity for the next owner to enjoy, restore, or reimagine a significant modernist estate with character, history, and long-term lifestyle potential. Whether used as a full-time residence, weekend retreat, creative sanctuary, or private gathering place, 301 Roaring Brook Road offers the space, privacy, and atmosphere that are increasingly difficult to find in Westchester. Located in desirable Chappaqua, the property is close to village conveniences, Metro-North, parks, trails, and the highly regarded Chappaqua school district. More than a home, The Roaring Brook Estate is a setting, a story, and a rare opportunity to become the next steward of one of Chappaqua’s most memorable properties.
