Completed in 1962, it is considered to be "one of the most well-known examples of mid-century modern architecture in Des Moines." It was designed by the prominent Chicago architect Ludwig Mies van der Rohe, and it is one of the first steel and glass modernist buildings in the city's downtown. Initially, the roof was designed to be suspended from two lengthwise trusses, similar van der Rohe's designs at the Illinois Institute of Technology in Chicago. That design was abdoned for a simpler and more direct design that features a steel-frame, glass-infill, and granite and travertine marble on the base.

It was built for the Home Federal Savings and Loan Association of Des Moines and later American Federal Savings, which failed in 1990 amid the country's Savings and loan crisis.
