How much did it cost to build the southdale mall?

Southdale Mall, located in Edina, Minnesota, opened in 1956 and was the first fully enclosed, climate-controlled shopping mall in the United States. The construction cost for Southdale Mall was approximately $20 million at the time. Adjusted for inflation, that amount would be significantly higher today. The mall was designed by architect Victor Gruen and has since become a model for shopping malls across the country.
