A unique and rarely available opportunity to own one of the last full floor apartments, redolent of the grand age of Manhattan prewar architecture, in what is considered to be the pre-eminent prewar condominium building in Manhattan! The present opportunity is for the purchase of two contiguous apartments, 5C & 5D, and to reconstitute them to the original grand design. Alternatively the apartments could be retained separately in their present 5.5 & 4.5 room configuration.Presently, apartment 5C (5.5 rooms) consists of the original large scale front public rooms including a stately, 'Parisien-style' living room & adjacent dining room (replete with original architectural detail and European mitering) -- extending 40 feet on Park Avenue; elegant entry foyer, master bedroom with en-suite bath, large square 2nd bedroom / library with en-suite bath. Apartment 5C is in excellent condition.Apartment 5D (4.5 rooms) consists of the original rear private quarters including 2 bedrooms & 2 baths, original eat-in kitchen and dining area. There are 10ft ceilings throughout both apartments. The rear apartment will require renovation but is perfectly positioned & suited to combine with apartment 5C.A reconstituted apartment 5C/D anticipates 9-10 beautifully proportioned rooms offering an optimal arrangement for practical, serene living and elegant formal entertaining. The public areas and private chambers can easily be deployed in a gracious and useful floor plan and given maximum separation by a lengthy and elegant hallway. The public areas would comprise a regal size living room & dining room (40 foot frontage on Park Avenue), a private elevator vestibule and oversize front hall gallery, a large eat-in-kitchen & butler's pantry and a large square library (bedroom). The private quarters would consist of 4 large-scale bedrooms with en-suite baths. There are three exposures and all major rooms are swept and burnished by western, eastern & southern sunlight. 525 Park Avenue is a fully staffed 'white glove' building with all amenities including ample private storage and is located literally at the apex of what is presently Manhattan's most desirable residential corridor, steps from the tranquility of Central Park.Please be advised that apartment 5D has limited access for showing subject to concluding a probate proceeding.
