We have gathered together some predictions regarding future houses: what will they be like? How will they be organised?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.
