Modify and re-purpose used shipping containers and stick them together to build a house. Architects, designers and builders have actually found a way to transform big boxes of steel into beautiful and fully-functional homes. With proper planning, you can endeavor to design and build a luxurious house for half the price of a “normal” house.  They are also very strong and very heavy, so they should be able to withstand just about any kind of storm — unlike an RV or mobile home. Using shipping containers to make a home or cabin in a more remote area should be quite a bit cheaper — this seems to be the main reason people like them.
