Philip Birnbaum and Alfred Kaskel also designed and constructed numerous apartment buildings scattered throughout Forest Hills. These include the Grover Cleveland, the Van Buren Apartments, the Thomas Jefferson, the Maplewood, the Richard Apartments, the Stephen Apartments, the James Madison, the Cedar Apartments, the Howard Apartments, the James Monroe, the Nathan Hale, the St. Regis, the Roanoke, and the Kennedy House. Birnbaum and Kaskel's buildings largely remain standing, and are distinguished by their spacious lobbies, interior courtyards with fountains, curved brick corner terraces, and sunlit exposures. Other notable high-rise apartment buildings include the Continental (on 108th Street), the Pinnacle, Parker Towers, the Windsor and a 17-story luxury condo building completed in 2014, the Aston.
