Mentioned as a good example of sustainable architecture, the Tulous Chinese architecture are constructed with rocks, bamboo, reeds, and wood. All material are local-made and natural.
Tulou are traditional communal residences in the Fujian province of Southern China, often of a circular configuration surrounding a central shrine. Some of these vernacular structures were constructed of cut granite or had substantial walls of fired brick. The end result is a well lit, well-ventilated, windproof, earthquake resistant building that is warm in winter and cool in summer.
