1924 floor plan of the Union Trust Building at 925 Euclid Avenue in Cleveland, Ohio, in the United States.

Designed by the nationally noted firm of Graham, Anderson, Probst & White for the Union Trust Company, the structure was the second-largest office building in the world at the time.

The site of the building is a semi-octogan with a rectangle. The Euclid Avenue entrance on the south was the main entrance. A lobby here directed office workers to the right, where a long corridor led to three elevator lobbies and a whopping 28 elevators to the upper 19 floors.

Passing north through the lobby led to the north-south banking hall for the wealthy. It was four stories high, with two mezzanines and a barrel-vaulted glass ceiling. There were only 10 teller's cages here. 10 banking parlors (where individuals could meet with bankers, or prepare documents for transactions) lined the west side of the main hall. There were four marble waist-high banking tables here, and two back-to-back marble benches. Three elevators next to the lobby led to the banking offices on the mezzanines above, and to the upper floors.

Where the east-west rectangle met the semi-octagon (e.g., where the two main banking halls met), there was a rotunda with a glass dome. To the west was the E. 9th Street entrance; to the north was the Chester Avenue entrance. (Two elevators in a foyer off this entrance led to the upper floors.)
