The state of Iowa has completed its purchase of office property at 6200 Park Ave. in Des Moines, Polk County real estate records show.

The state paid William C. Knapp LC $18 million for the 15.2-acre property that includes a 138,978-square-foot, two-story office building. Construction of the building was completed in 2002, records show.

In August, the Executive Council of Iowa approved buying the property. State officials have said agencies currently located in the Henry A. Wallace Building at 812 E. Grand Ave. would be relocated to the Park Avenue property. Those agencies include the Iowa Department of Agriculture and Iowa Department of Natural Resources.

The future of the Wallace Building, which has had several structural and maintenance issues since its construction in the late 1970s, is uncertain.

The Park Avenue ­building includes warehouse space, a fitness center with showers and lockers, and a grab-and-go market with lounge, according to a brochure about the property. The building most recently was occupied by Wells Fargo.

The Park Avenue property, because it is now state owned, is tax-exempt and won’t generate any property tax revenue. In the 2021 tax year, the property generated $483,304 in property taxes for the city of Des Moines, Polk County, Des Moines school district and other taxing entities.

The property is valued at $9.3 million.

The real estate transaction was recorded Sept. 29.
