This is my house in the future. It will be built under the ocean. My house will be surrounded by water and thousands of sea creatures such as fishes, octopuses, jellyfishes, turtles and colorful coral reefs. There will be a vegetable garden in my house so that it provides oxygen for my family. A submarine is also needed to take me to school.

My future house will use water to power it. There will be a lot of smart machines such as a fridge, a microwave oven, a dishwasher and a washing machine. Most of them will be automatic. They might refresh food, cook meals and wash dishes and clothes.

I will also have a super smart computer in my house. It will help me surf the internet, update information, go shopping and keep in contact with friends from all over the world. Sometimes, I will not go to school because I can stay at home and join online classes by using my computer.
