640 Park Avenue is an Neo Italian Renaissance style co-op in the Lenox Hill neighborhood of Manhattan’s Upper East Side. Truly a spectacular building and a prime example of the style of times. Built in 1914 and designed by JER Carpenter for the developer S. Fullerton Weaver. Completely clad in limestone, the building has beautiful detailing and from the photos it’s obviously been very well maintained over the years, hardly a surprise considering that an apartment in the building will set any would be owner back at least $20 million. Perhaps what makes this building so “special” is that it only has 13 floors and 12 apartments that are all full floor sized, the epitome of UES exclusivity. While typically in buildings of this sort residents like their privacy, one of notoriety in particular who sold his apartment was Dick Fuld, of ex-Lehman Brothers.
