Architecture and building history
Completed in 1931, 778 Park Avenue occupies the northeast corner of East 73rd Street. Rosario Candela's design combines a broad base with upper setbacks, bringing variety to the building's exterior and to its apartment positions.
The building received a conservation award from Friends of the Upper East Side in 1983. That architectural history helps explain its place in this guide, but a purchase still turns on the condition and arrangement of the individual residence.
What to compare in the apartment
Compare the main entertaining rooms and the private bedroom areas together. An apartment may have generous room counts yet require substantial work to suit a different way of living.
Pay attention to the elevation at which the residence sits and the direction of its windows. Higher setback apartments and lower full-floor or partial-floor residences should be compared separately. Any maisonette or terrace offering requires a clear account of access, private-use rights and the current approved plan.
The location
The East 73rd Street location allows a direct comparison with 770 Park and the other Candela buildings nearby. Walk the cross streets toward Madison Avenue to understand the relationship between the apartment's immediate setting and the surrounding neighborhood.
Services, maintenance and purchase requirements
Request the current service schedule and maintenance breakdown for the apartment. Establish which services are included, which carry separate charges and whether storage or other ancillary space transfers with the shares.
A co-op purchase involves shares in the building corporation and a proprietary lease. Have your attorney review the financial statements, minutes, insurance and any assessment notices. Confirm the current requirements for financing, liquidity, intended occupancy, ownership structure, subletting and renovations with the managing agent. Published summaries can lag the governing documents.
Compare the complete cost of ownership with the apartment’s condition and the work you intend to do. A recognizable address does not establish the condition of the home or the co-op’s finances.
Where it fits on a shortlist
