The tiny-house movement (also known as the "small house movement") is an architectural and social movement that advocates for downsizing living spaces, simplifying, and essentially "living with less." According to the 2018 International Residential Code, Appendix Q Tiny Houses, a tiny house is a "dwelling unit with a maximum of 37 square metres (400 sq ft) of floor area, excluding lofts." While tiny housing primarily represents a return to simpler living, the movement was also regarded as a potential eco-friendly solution to the existing housing industry, as well as a feasible transitional option for individuals experiencing a lack of shelter.
