The social movement to live in houses that are as small as possible originated in the USA and aims to conserve resources while focusing on the essentials. There, the movement also received a strong boost from the financial and real estate crisis starting in 2008. Tiny houses are freestanding and immovable housing units with a maximum area of 45 m2. In Switzerland, this form of housing is not very widespread, as it is often very difficult to find a parking space legally.
