This is a rare opportunity to own a 30-foot wide mansion located between Fifth and Madison Avenues. The property has tremendous potential and similar renovated properties in the area have sold for $50M to $60M. This mansion has been in the same family for 46 years but is now being sold vacant. It boasts a beautiful French Renaissance Limestone Facade and spans over 13,000 square feet with five stories and a lower level, serviced by a four-passenger elevator. The lot size is 30′ by 100′ and currently, the mansion is divided into a home office with front and back garden and separate entrance on the first floor and lower level. The owner’s duplex is on the parlour and 3rd floors with original details, wood-burning fireplaces, and a landscaped terrace. The 4th and 5th floors have four one-bedroom apartments with beautiful original details and a central staircase topped by a sun-flooding skylight. The mansion was built in 1893 as a single-family home and designed by Lansing C. Holden for Josephine and William Buchanan. It is located on a quiet, tree-lined street without crosstown traffic or buses, just three properties away from Central Park. This prime Upper East Side location is close to high-end Madison Avenue shopping, dining, and celebrity hotspots. Bring your architect/contractor to make this property your dream home.
