Eyeing Russia, Estonian Company Creates Underground Hamster City for Humans

An Estonian company is manufacturing large plastic tubes that link together like Lego blocks and can even withstand enemy fire. They’re kind of like hamster tubes turned into modular homes, buried under the ground.
There is an office model, a bedroom, bathroom, shower, freezer and even a morgue, according to Terramil, the company that makes it. The units start at $20,000 for a bedroom and more than $40,000 for a shower unit.
