Here’s a novel way to slash your business expenses in half: Relocate 100 feet underground.

In the Midwest, many businesses have done just that.

In states like Missouri, Kentucky and Pennsylvania, there’s a growing number of firms doing business in subterranean spaces that were once mines. Starting in the 1960s, these spaces were rehabilitated for commercial use.

SubTropolis, in Kansas City, Mo., is a well-known example.  The underground business complex was an active limestone mine in the 1940s, owned by real estate firm Hunt Midwest. As mining started to taper off, it left a vast network of empty caves.
