Reaching a height of 20 stories, the former United Office Building was the tallest building in Niagara Falls until 2005. Now a luxury hotel called The Giacomo, the building was erected in 1929 by Frank A. Dudley, who was the president of the United Hotels Company of America. The building is considered one of the finest examples of Art Deco architecture in Western New York and is known for its use of Mayan Revival decorative terra cotta and sculptural elements. The setback floors at the top of the building feature friezes depicting ancient Mayan gods. The hotel opened in 2010. The building was added to the National Register of Historic Places in 2006.


The former United Office Building was erected in 1929 and remains one of the city's best-known landmarks. It was the city's prestigious office building for several decades.

Frank A. Dudley (1864-1945) was a prominent politician, businessman, lawyer who played a large role in developing the Niagara Falls area in the late 19th and early 20th centuries. He co-founded and became the president of the United Hotels Company of America (UHCA) in 1910, which eventually became the largest hotel chain in the country by 1926 with 23 hotels and more than $76 million in investments (one of these hotels was the former Hotel Niagara, which is located across the street). The building housed many of the city's leading professionals and businesses, including attorneys, insurance companies, and investment brokers. The UHCA housed its offices in the building as well and Dudley's law firm, Dudley, Gray and Phelps. The building also included two restaurants, clerical and secretarial services, and full car service in the garage next door (the garage was torn down in the 1960s).

Occupancy of the building remained stable until the 1970s when tenants began moving to the suburbs. Two plans to convert the building into condominiums fell through and the it remained vacant for many years until The Giacomo opened in 2010. The building also includes a restaurant and 24 upscale apartments.
