Rare opportunity to combine two full floor apartments in one of Manhattan's most prestigious white-glove condominiums on Park Avenue.Spanning over 6500 square feet on the 17th and 18th floors with high ceilings, oversized windows, and wonderful Park Avenue and open city views,  this potential six bedroom duplex with maids room would not only have a 30-foot by 21-foot living room, but it would also have the same size media room.  The master bedroom suite has his and her bathrooms along with a large dressing room.  A grand staircase would connect the two floors with an elevator entering into the apartment.  Several apartments in the building have been duplexed and the basic footprint of the floors is very flexible and can be designed to your specifications.Each apartment comes with a large private storage unit.This 43-story limestone tower was completed in 2000 and inspired by the scale and grandeur or the prewar buildings on Park and Fifth Avenues.  The building offers a full-time doorman, concierge, valet, fully-equipped fitness center, conference room, dining salon, and kitchen for Chef Daniel Boulad, the exclusive caterer for 515 Park Avenue.
