This very handsome and dignified apartment building was erected in 1928 and is almost an identical twin of the adjoining building to the east, No. 530, which was erected one year earlier.

Both buildings were converted to cooperatives in 1950. This building has 47 apartments, one more than No. 520.

The mid-block buildings both have limestone bases that are rusticated around the entrances. The entrances are slightly different: 520 has a rectilinear entrance and this has an arched entrance, which is a bit more impressive. Both buildings have red-brick facades interrupted by broad bandcourses and they permit protruding air-conditioners.

This building has consistent multi-paned fenestration, but does not have the very handsome and large bay windows facing a wide, handsomely gated alley between the two buildings as does No. 520.

Both buildings are very close to Carl Schurz Park, whose entrance is at the East End Avenue corner of this street and they are across 86th Street from the charming townhouses along Henderson Place, one of the city’s few small mid-block mini-streets.

Although neither building has sidewalk landscaping, both are among the most desirable in this area that is popular with families because of the park and excellent private schools in the neighborhood.

There is excellent crosstown bus service, but the express subway station at Lexington Avenue is quite far away.
