Back in the 70s Banker Herbert Allen Sr., one of the most affluent businessmen on Wall Street at the time, purchased the Upper East Side penthouse at 733 Park Avenue for $526,500, which has recently been sold for $2o million.
The foyer features two-floor windows and a spiral staircase connecting the 30th and 31st floors of the penthouse. The duplex three-bedroom pad boasts a private elevator, an all- marble bathroom, a unique hand-laid parquet floor and three magnificent landscaped terraces covering 1,250 square foot. The behemoth bedrooms feature large windows overlooking awesome views of Central Park – actually no other building from Park Avenue offers such views since this is the tallest residential building on this street.
