This flood-proof parking garage could automatically pop-up when it rains
During extreme storms, it's common for city infrastructure - from roads to subways to parking garages - to flood.
Architects from Danish firm Third Nature want to build garages that can cope with future storms. They designed a garage that could automatically move up and down as its water reservoir fills with and empties floodwater.
Check out the conceptual structure, called Pop-Up, below.
