Riverview Square
140 N. Phillips Avenue, Sioux Falls SD
This 56,000-square-foot building with underground parking was originally home to the IBM office in Sioux Falls and later the DM&E railroad headquarters on Phillips Avenue in downtown Sioux Falls.
The four-story building was completely remodeled inside and out, and current tenants include local and national law firms, national trust companies and retail banking operations. Its location has some of the best views of the Big Sioux River in downtown Sioux Falls.
