The Arkansas Power and Light Building is a building in the city of Little Rock, Arkansas. The building is listed in the National Register of Historic Places. Now also known as the Entergy Building, it was the first office building in downtown Little Rock built in the International style. Designed by the architect Fred Arnold of the Little Rock architectural firm of Wittenberg, Delony & Davidson in 1953, it was not completed until 1959 due to uncertainty over the utility's requested rate increases and the expiration of laborers' union contracts.
Acclaimed at the time for its "modern" look, the building features marble panels and glass curtain wall, above a single-story, curvilinear brick masonry section at the western end. It was one of Little Rock's first buildings built after the city formally adopted its "Little Rock 1969" master plan. The plan controlled new commercial design and encouraged private-public partnership for downtown beautification over the next decade.[2]
The building at 900 S. Louisiana St. houses Entergy Arkansas, the successor to Arkansas Power and Light Co. It has continually been the utility's headquarters.[3]
