This attractive building in the heart of the desirable Carnegie Hill neighborhood was erected in 1923 and converted to a cooperative in 1954. The 14-story edifice has 56 apartments. It was designed by George and Edward Blum whose other Park Avenue buildings include 555, 791, 830, 840, 875 and 940.A nice feature of the building is that it has arched windows on the 3rd, 6th, 9th and 12th floors. The building, however, has inconsistent fenestration, protruding air-conditioners and no sidewalk landscaping. Not to far to the east of this building on 88th Street is the entrance to P.S. 169, the Robert F. Kennedy School. There are many fine private schools in this neighborhood as well as many cultural and religious institutions. The building is convenient to public transportation and excellent retail.
