The Simms Building is historic high-rise office building in downtown Albuquerque, New Mexico. Designed by Flatow and Moore and completed in 1954, it was the city's first large-scale modernist building and is regarded as "Albuquerque’s best example of the International Style". The building was added to the New Mexico State Register of Cultural Properties in 1997 and the National Register of Historic Places in 1998, only 44 years after it was completed.
