Organized with window walls of offices facing north and south and an elevator core anchoring its west end, the First National Bank Building began as a twelve-story building. In 1978, twelve more matching stories were added, making the building Midland’s tallest. On the exterior, horizontal bands of pale-blue glass windows alternate with white marble spandrels. In the center of each of the five window bays a vertical yellow panel extends from the second- to the twenty-second floor. The window wall of the double-height penthouse floor is recessed beneath the building’s parapet.

The First National Bank previously occupied the dignified, limestone-faced stripped

classical building (1937, Wyatt C. Hedrick) two blocks to the east at 103–105 W. Wall, consisting of a two-story banking hall and an adjoining nine-story tower. It was rehabilitated in 2018 by Rhotenberry Wellen Architects as office space, with a new parking garage behind. Sharing the block front with the bank is the former Midland Hilton, now the Doubletree by Hilton Midland (1976, 1982, Pierce, Norris, Pace and Associates; 117 W. Wall), a twin-towered, eleven-story, curtain wall-faced complex that uneasily straddles two antithetical trends of the 1960s, New Formalism and Brutalism.
