Kemper Arena was built in 18 months in 1973–74 on the site of the former Kansas City Stockyards just west of downtown in the West Bottoms to replace the 8,000-seat Municipal Auditorium to play host to the city's professional basketball and hockey teams.

The arena was the first major project of German architect Helmut Jahn, who was to go on to become an important architect of his era.

The building was revolutionary in its simplicity and the fact it did not have interior columns obstructing views. Its roof is suspended by exterior steel trusses. The nearly windowless structure contrasts to Jahn's later signature style of providing wide-open, glass-enclosed spaces. Kemper's exterior skeleton style was to be used extensively throughout Jahn's other projects.

The building cost $22 million and was previously owned by the city of Kansas City, Missouri.
