Perfectly located on a picturesque tree-lined street in the Upper East Side's Historic District, this splendid, perfectly appointed townhouse is an ideal combination of period detail and modern convenience. Eighteen feet in width, with 5,300 interior square feet and a divinely large 1,700 square foot garden just outside, the house imparts a marvelous luxury of space and is gloriously light-filled.

Accessed directly from East 75th Street, the entrance vestibule and hall open to a large and welcoming Dining Room that incorporates a staircase to the upper levels. A coat closet is conveniently accessible. Nearby, the delightful Garden Room has a decorative fireplace and a pair of French Doors with arched transoms leading to the Garden.

The Garden is magical. With a seamless transition from indoors to out, the spectacularly designed terraced garden is inviting and vast, extending more than 35 feet beyond the house. Two distinct levels and a periphery of pretty trellising and lush plantings are an oasis in the city and are underpinned by a gorgeous stone terrace dotted with embedded twinkling fairy lights.

Beyond, and also accessed by a separate front entrance, the well-appointed eat-in chef's Kitchen offers a panoply of top equipment and a built-in banquette. Below, the finished cellar includes a Recreation Room, a Laundry Room, a full Bathroom, well-organized Utilities and Boiler Rooms, and very ample closets.

On the second floor, the amply-sized Living Room is nearly 35 feet long and has pleasant and leafy outlooks through a treble-paneled arched window with box plantings. It also features an attractive stone-mantled decorative fireplace. Bordered in one section by a balcony that is open to the Dining Room below, the Living Room has a marvelous sense of space and size. Nearby, the handsome Library is a quiet refuge enhanced by a decorative fireplace. French doors with a balcony and a large window look over the stunning garden below.

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.
