First of all, technology will be an effective tool to help improve our quality of life. There will be smart homes with high-tech appliances. People will use a phone app connected to home equipment and give orders. More houses of the future will be smaller because of the living alone trend. Smaller space makes one room become multifunctional: kitchen, dining, sleeping, and working. People also love the idea of motorhomes which helps them to change their locations. Imagine living in different cities every month, thats fantastic! Another idea of future houses states that every individual house and building will become a power plant with renewable energy sources. There will be different alternative energy sources to use in houses because people care more about the environment.
