As far as I'm concerned, houses in the future will be likely to be built with environment-friendly materials. The materials are wonderful, that can not only produce electricity by take in air and sunshine, and also keep the houses warm in winter and cool in summer. On addition, if there is an accident happen in the house, the host will receive an alarm call immediate. Most importantly, once some disasters such as earthquakes or storm happen, the house will fly away to avoid the danger.
In a word, as the development of science and technology, I believe my dream will be come true. And the houses in the future will become comfortable to live in.
