Hunt Midwest SubTropolis is the largest underground business complex in the world. This subsurface development is now home to more than 50 local, national and international businesses. Tenant companies include warehousing, cold storage, light manufacturing and office operations—each attracted by:
low lease rates
low utility costs
comfortable surroundings for higher worker productivity
maximum flexibility for expansions and seasonal surges
convenient on-site management, maintenance and security
SubTropolis was created through the mining of a 270-million-year-old limestone deposit. In the mining process, limestone is removed by the room and pillar method, leaving 25-foot square pillars that are on 65-foot centers and 40 feet apart.
The pillars’ even spacing, concrete flooring and 16-foot-high, smooth ceilings make build-to-suit facilities time and cost efficient for tenants. A tenant requiring 10,000 to one million square feet can be in their space within 150 days. SubTropolis is completely dry, brightly lit, with miles of wide, paved streets, and is at street level.
Hunt Midwest SubTropolis sets the standard for subsurface business developments.
