The main frame of the skyscraper rises 32 stories, capped by two asymmetric
spires, one extending for seven additional stories. The roof height of the building is 496 ft (151 m), the top floor is 489 feet (149 m), and the spire reaches 632 ft (192.6 m). Its nickname,
Cathedral of Finance, alludes both to the building's resemblance to a cathedral—with its tower over the main entrance and octagonal
apse at the opposite end—and to New York City's
Woolworth Building, which had earlier been dubbed the
Cathedral of Commerce. Rowland designed furniture for the bank's offices as well as tableware, linens, and waitress uniforms for a restaurant in the building. The building's three-story, vaulted lobby is lavishly decorated with
Pewabic and
Rookwood tile. The semi-circular exterior domes are filled with
Pewabic Pottery;
Mary Chase Perry Stratton worked closely with the architect in the design of the symbolic decorations. (
See Savage, infra.) A
Monel metal screen divides the lobby from the banking hall on the second floor, the screen features a clock in the center designed by
Tiffany. The building includes works by muralist
Ezra Winter in the mosaic above the main lobby desk and the mural at the end of the banking hall. The large mosaic is of a pine tree and text that states the Union Trust Company's purpose for the building, "Founded on principles of faith and understating, this building is erected for the purpose of continuing and maintaining the ideals of financial services which promoted the organization of the institution". The mural highlights Michigan's industries such as manufacturing, farming and mining. In order to dampen the sound in the banking hall, its cement-plaster ceiling features a hand-painted canvas ceiling, which was stretched over a mat of horsehair. ==Innovations==
