Long time - no new info here...
I told Annie, our international student guest from Taiwan that we enjoyed learning of indigenous housing information from other countries. She said she was going to send me some information and even though she was busy getting caught up on her studies after her visit here, she kept her word and sent a link to Fujian indigenous architecture.
I touched on this subject a bit 4 years ago when John, a professor in Xiamen told me of it.
Annie knew another name for this architecture, Tulou, and sent me a link to more information.
Tianluokeng Tulou cluster
As I was studying up on the subject a bit I found that these earthen homes worked as a home for family clans but also as a fortress against groups of armed bandits -sometimes up to 10000 of them and even an army cannon firing 19 rounds against the wall but only making a small dent.
The lower walls may be of rammed earth with stone, lime, sand depending on the local flood level then go to earth above. There were no windows in the low levels as they were storage, foundation and protection - up to over 6 feet thick tapering to 3 feet thick at the top..
They were even built to a CODE - how about that..... http://en.wikipedia.org/wiki/Yingzao_Fashi
written around 1065 AD. That makes ours a newcomer....
The upper windows could be used for shooting from and in some cases there were special corridors for getting to defense positions quickly.
No concrete reinforcement here. Earth, stone, bamboo, sticky rice. Unconventional by our standards but some have stood for over a thousand years.
How about a well in your own kitchen -
More info including enough instructions to build your own I think.... at the link Annie sent mehttp://en.wikipedia.org/wiki/Fujian_Tulou
