In the Hokkaido town of Taiki-cho, the winters are cold and isolated. But the architecture and lifestyle in this natural state of coldness and inconvenience can also be seen in a positive way. Sustainable approaches that do not rely on machinery can be found in every region. These include gazing up at the starry sky while wearing a coat, jumping from a hot sauna into an intensely cold lake (a special Finnish pleasure), and Japanese hot springs. In Taiki-cho, beautiful water and greenery exist side-by-side with the severe conditions. What would happen if you tried to create a similar situation with artificial materials? Imagine what kind of building you could create without worrying about the locality of the materials. Please design an exciting facility to enjoy the environment in Taiki-cho. Insulation is okay, but please create something that could be used for a short period that incorporates exciting elements like a bonfire – something that human beings have used since primitive times – or the sound of steam.
