Tiny houses are homes that occupy around 50 square meters of land. They're appearing more and more in recent years, especially in crowded cities. Many of them feature unusual layouts and creative design. Our guest, architect Sugiura Denso, introduces clever techniques that are used to make the most of limited space. We follow the construction process from start to finish. And we take a look at low-cost prefabricated tiny houses, measuring as little as 12 square meters.
