Triple mint 22 foot wide townhouse, fully renovated top to bottom and offering significant space, volume, light, and quality. In a market of homes in need of renovation, this is the elusive "turnkey" home. The current owner gut renovated the home over the course of nearly a decade; it has been meticulously maintained, and is now prepared for its new owner. The house is approximately 9,000 square feet (8,200 above grade), situated on a 100 foot deep lot, and sits on the south side of 73rd Street just east of fashionable Madison Avenue. There are six stories, six bedrooms, six full bathrooms, and three powder rooms. Originally built in 1885, the facade is Neo-Grec Brownstone, fully restored. Enter through a securitized gate to a private foyer entry, and up we go. GARDEN LEVEL: You are greeted by an enormous, full-width gallery and library with a wood-burning fireplace and significant cloak storage. A grand, steel (hardwood wrapped) staircase leads all the way up through the house, and opens to a crowning skylight allowing light through the entire core. Additionally, an elevator goes from bottom to top. Through here is the eat-in kitchen, complete with Sub-Zero and Miele appliances, quartz countertops, significant custom cabinetry, a pantry, and a back office and stair. The kitchen leads graciously to a back garden bathed in southern light and ultra-quiet and private. PARLOUR FLOOR: Entered either via the main stair or rear secondary stair, the parlour floor is an open entertaining space with significant ceiling height and is appointed with perfect luxury touches. There is a formal living room and dining room, each with its own fireplace, a butler's pantry, juliet balcony, wine room,and powder room. THIRD FLOOR: The primary suite occupies this entire floor. Here lies a large, north-facing full-width bedroom with fireplace, a custom built-out dressing room, and a windowed bathroom with a private terrace and all spa-like features: a Jacuzzi tub, steam shower, water closet, and separate vanities. FOURTH FLOOR: Twin guest suites occupy this floor, each with a custom built-out closet, and their own three-piece bath. There is a laundry room on this floor as well. FIFTH FLOOR: On this floor are three bedrooms and two full bathrooms, as well as additional closet space. This floor can easily be used for guests, children, or for additional in-house amenities such as an office, gym, pilates room, or additional storage. SIXTH FLOOR: Added on by the current owner, the sixth floor is a penthouse-like entertaining and recreation room with a private terrace. Bathed in light from multiple skylights, this room can be used for gaming, exercise, recreation, or as additional sleeping space. It has a wet bar and powder room as well. The CELLAR of the house was dug out and contains a staff room, significant amounts of storage, a gym, and bathroom. The mechanicals of the house are second to none in the market today. There is state-of-the-art infrastructure such as an independent generator, a water filtration system, full soundproofing throughout, individually controlled HVAC in each room, a full-home speaker system, smarthome, and 600 amps of electrical service. Truly, a purchaser need not do any renovation, and can simply "bring their toothbrush" to this magnificent Upper East Side mansion. Located in the absolute heart of Manhattan's most famous, glamorous, and elegant neighborhood, the Upper East Side, 40 East 73rd Street boasts simple and immediate access to world-class shopping, culture, restaurants, foundations, organizations, transportation, and of course, Central Park.
