The Primary Bedroom suite extends over the entire third floor. The gorgeous Primary Bedroom has a decorative fireplace as well as oversized windows with Juliette balconies offering pretty outlooks to the gardens and the landmarked townhouses along East 74th Street. The Bedroom is supported by a cheerful and sunny Sitting Room, a very spacious bathroom, and copious closets, including a very large walk-in-Dressing Room. The fourth floor is comprised of three Bedrooms. Two of these are very large and both are anchored by decorative fireplaces. One of these has an ensuite bath with a skylight. There is also a charming third Bedroom with a very high ceiling, as well as an additional bath, both fitted with skylights. Throughout, the impeccable stewardship of the present owner is evident. All systems, such as multiple-zone central air conditioning, security, lighting, and Crestron, have been perfectly maintained and updated. In addition, hardwood floors, custom millwork, and meticulously restored original features underpin an elegance that extends to every detail and has been executed with great care. Initially conceived as part of a complex of “automobile stables” that occupies 168-176 East 75th Street, this house and its neighbors were designed by Hill and Stout in 1902. Following the traditional layout of a carriage house and intended for use by Manhattan’s millionaires, their design incorporates a picturesque roofline that alternates gables and dormers and is faced in a handsome design of red and blackened clinker bricks. This marvelous townhouse, richly storied and impeccably brought to today’s highest standard, is truly perfect.
