The World’s Largest Underground Business Complex.®

What is SubTropolis? 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 120 days. SubTropolis is completely dry, brightly lit, with miles of wide, paved streets accessed at street level.

“As a nationwide distributor, timely delivery of our products to consumers is critical. Locating in SubTropolis has allowed us to reach 90% of the United States within two days and in these uncertain times, quick, reliable food delivery is more important than ever.”

Janna LandCo-Founder & COO

“We looked at SubTropolis because of reduced rent cost and very controlled utility costs with no expense during the winter months to heat our building as well as very low costs during the summer months to control humidity and maintain a cool climate.”

Gina DannnerCEO of Mail Print

“The team at Hunt Midwest was able to accommodate our need for additional space so we could focus on the rapid changes impacting our business and ramp up operations as soon as possible.”

Janna LandCo-Founder & COO

“In the dead of winter and summer, we’re saving $35,000 a month on our energy bills by being here.”

Mark MathesCEO of Vanguard Packaging

“It’s 70 and overcast everyday, regardless of what’s going on outside. We load our trucks… unload our trucks in perfect weather conditions. It’s truly a green environment. We’re probably using about 75 percent less electricity underground than we would in an above-ground facility. Whether it’s electronics or whether it’s food, you don’t have temperature and humidity fluctuations and so you don’t have any condensation, moisture building up in anything. From that standpoint, in my opinion you can’t beat it.”

Joe ParisPresident of Paris Brothers

“The facilities at SubTropolis are a great solution for Ceva’s current and future warehousing needs. The consistent conditions and ability to easily expand were two key reasons we chose SubTropolis for our facility.”

Craig WallaceCEO and North America/Pacific Zone Director - Ceva Animal Health

“Stringent industry standards require pharmaceutical companies maintain specific temperature and humidity levels. The consistent control room temperature ranges in the underground allow us to efficiently meet these requirements. Onsite security staff provide an additional level of security and peace of mind to our team.”

Teneshia PowellSenior Production Manager

“SubTropolis is a good fit for Leggett & Platt CVP because of its proximity to the Ford Kansas City Assembly Plant, where the Transit is built. We also found the underground to be a cost-effective location in an ideal environment for our commercial equipment installation operations.”

Vice PresidentLeggett & Platt CVP
