Federal Building, Government building in Little Rock, United States.

The Federal Building at 700 West Capitol Avenue is a seven-story Modern structure occupying an entire city block. Its curtain-wall exterior has narrow windows separated by limestone spandrels on all four sides. The recessed south entrance consists of several pairs of double doors flanked by gold-colored grillwork.

The Federal Building was built in 1962 to designs by the Little Rock firms Swaim & Allen & Associates and Ginocchio, Cromwell & Associates, with Robert E. McKee General Contractor, Inc. of Dallas as builder. It was listed on the National Register of Historic Places in 2015.

The building shapes Little Rock's skyline through its plainly designed form without decorative elements. Visitors notice immediately how different it stands from older administrative structures in the city.

The Federal Building occupies a full city block at 700 West Capitol Avenue, next to the Richard Sheppard Arnold United States Post Office and Courthouse. Its recessed south-facing main entrance, flanked by gold-colored grillwork, is reached through several pairs of double doors. The upper floors have narrow windows set between limestone spandrels on all four sides.

The Federal Building was added to the National Register of Historic Places in 2015, more than fifty years after its 1962 completion. Its listing rests on the curtain-wall design by Swaim & Allen & Associates with Ginocchio, Cromwell & Associates, showing that postwar Modernism now counts as historic architecture.
