This house is not really a seesaw, it is firmly planted in the earth. Well, at least half of it is.When a structure hangs out without anything supporting it, it is called a cantilever. This house in Surrey England is an example of CANTILEVER EXTREME! And the story is that you can rent it and see what it is like to live in it! This video has the architect, a man from the Netherlands named Winy Maas, describing why he created this design. We want to visit and see if we eat too much and walk in the living room, if it might fall over. Hopefully not.
