The National Register nomination describes its importance as "the purest example of Neo-classic style in Sioux Falls. The combination of classic elements and internal structural innovations of the early twentieth century, such as steel doors and trim painted to resemble wood and a nine-ton glass floor, enhance the architectural importance of the structure. The use of steel and glass were unique at that time in the city."[2]

The building has one of the largest Masonic libraries in the United States. The library has more than 22,000 volumes. The building also has a museum on its second floor.[2]
