In Europe and North American，the size of an average family is getting smaller，but homes are not.In many countries they are getting bigger.Bigger homes are more expensive and heating them in cold weather is worse for the environment.Many people believe it's time to think again about the size of our homes.Sixteen-year-old Austin Hay is building a small home with four wheels.It's got everything important，including a shower room，a kitchen and a bedroom.
    "When I was a kid，I wanted to build a tree house，" Austin explains. "But the house is on wheels and that's a lot cooler."
    During the week，Austin is busy with school work.He only works on his house at the weekend. "At the moment I'm working on the doors.They are quite easy，so my dad isn't helping me.He only helps with the difficult things."
    There isn't a fireplace in his little house，so in winter Austin will move back to his parents' house.And what is in the future？ "University is very expensive in America，but it will be cheaper for me because I can take my little house with me.I can live in it anywhere."
