Alterra IOS Expands Chicagoland Portfolio

Industrial outdoor storage provider Alterra IOS has acquired a twelfth site in the Chicagoland area.

Located at 216 W Diversey Avenue in Elmhurst, the 2.8-acre property includes 35,000 square feet of warehousing space, designated office space, and is fully leased to a regional leader in the heavy-duty truck sector.
