I live in Fujian Province, China. The climate is sub-tropical monsoon. I want to build a 3 meter diameter raised bed. Originally, I was planning to build a geodesic dome greenhouse, but I think the summers are too hot for this.
Instead, I want to build a 6 meter diameter earthbag round wall (3 meters high) around the garden for wind protection and privacy. The style would be similar to the Chinese Hakka houses. I don't want to build an enclosed roof, only a roof to cover the walls and 1.5 meters inside the garden round house.
