In China, every day, numerous buildings are demolished and new ones are constructed. Although old houses are torn down, the doors often survive and are transported to secondhand markets on the backs of recycling tricycles, where they are repurposed. This serves as a natural example of sustainable design.

Why choose doors? Because one of the principles of environmentally sustainable design is "making the most of what you have."
