This house is a part of that outstanding group of neo-Federal townhouses which extends along the west side of Park Avenue, between East 68th and 69th Streets, sometimes referred to as the “Pyne-Davison Blockfront” due to the uniform architectural quality of these houses.
No. 680 Park Avenue, formerly the handsome townhouse of Percy Rivington Pyne, occupies a conspicuous site at the northwest corner of East 68th Street and Park Avenue. It was designed in the neo-Federal style by the architectural firm of McKim, Mead & White, and built in 1909-11. Percy Pyne was a New York financier and philanthropist; he resided here until his death in 1929. The house was sold in 1947 to the Chinese Delegation to the United Nations which in turn sold It to the Soviet Mission to the United Nations.
