When you travel around the European countryside，you can be lucky to find an unusual house-a tiny house．
Tiny houses are hand built home structures that are generally from 100to 300square feet（平方英尺），often on wheels．A tiny house is small enough to pull，so you can use a truck（卡车）to haul it around the countryside．If you decide to move to a new place，or just feel it necessary to change your living environment，you can take your house with you because it is easily moveable and convenient．
Tiny houses are built from green building materials．They are quite suitable for a single person or couple who have a strong wish to live simply．Some tiny houses are designed more like Victorian（维多利亚女王时代的）country houses with very simple small windows and halls．Others are simpler structures-comfortable but cute structures with folding furniture The small houses need fewer materials to build and they use less energy．But many tiny house builders create a separate bath house nearby to leave more living space and create private space for bathing and personal care．
Tiny houses are for people who don’t ask for too much．Besides，tiny houses are for people who are interested in a green lifestyle．
