There are some pictures of my dream house. My dream house will be a normal house but it so comfortable, too. It will be in the countryside. I like this place because the weather will perfect and the air so clean. Surrouded it by many tall green tree and white fences. There will be a big yard to play my favourite sports and games. There will be a large garden behind the house with many kind of different flowers and colorful butterflies. From the window of my bedroom, i can see them. My house will have a big garage so i will put my super car in it. There will be two floors with seven rooms: a bedroom, a livingroom, a kitchen, a bathroom, two halls and a big attic. My house will use wind energy and solar energy. I will have all modern robots in the world and they will do and control all thing for me. My house will use all automatic machines as: automatic dishwasher to wash and dry dishes, automatic washing machine to wash and dry clothes... In the living room, there will have a wireless Tv to watch my favorite films from space and order food in the market. In my bedroom, i will have a super smart computer to suft the internet and contact with my friends from the other planets. That's my dream house. For me it so perfect. I hope it will be true in the future.
