This building consists of duplex units of the type used on West 67th Street, although in the plan of this building many large double-story living rooms were built instead of studio spaces. So successful was the cooperative arrangement in this building, that the developer took title to the adjoining lot on the southeast corner of 67th Street and Lexington Avenue, as well as another property on the northeast corner of Lexington and 67th Street in 1907. Both of these soon were developed with cooperative apartment houses.
