The promotors of SubTropolis call it the The World’s Largest Underground Business Complex.
The industrial and warehouse complex is in an old limestone room-and-pillar underground mine near Kansas City in Missouri, USA.
They’re so confident that the mine-into-business-park concept will take off that they’ve gone so far as to trademark™ the name. They also have a mascot called GUS – Great Underground Space.
The company has nearly 5,000,000 square feet of industrial space for lease in SubTropolis which is adjacent to Ford’s Claycomo vehicle plant.
According to a Bloomberg piece tenants have reported saving as much as 70% on their energy bills while rents of $2.25 per square foot is about half the going rate above ground. Some 1,000 people already work in SubTropolis.
