Perhaps Abraham's best known work of architecture is the Austrian Cultural Forum New York (1993-02), at 11 East 52nd Street; a building ingeniously arranged onto a site only 25 feet wide. Architectural historian Kenneth Frampton as recognized the Austrian Cultural Forum as "the most significant modern piece of architecture to be realized in Manhattan since the Seagram Building and Guggenheim Museum in 1959." Another notable project, "Musikerhaus" or "House for Musicians" (1999), in Hombroich, near to Düsseldorf, Germany. The built atop a former NATO missile base. Abraham adapted the site for reuse as an artists' residence and exhibition gallery. Abraham's "Musikerhaus" was completed posthumously, under the supervision of Abraham's daughter Una, in 2013. In 2015, The German Architecture Museum (DAM) identified Abraham's "Musikerhaus" as a significant new building constructed in Germany.
