Mr. Rawles,
In your 09/19/2005 blog, you asked for input on different architectural techniques related to a retreat. Following is information on a type of construction that has some interesting potential. Take a look at the video at http://archnet.org/library/files/one-file.tcl?file_id=1385 . It is a high-resolution Windows Media Player file showing construction of sandbag shelters using very low tech methods and tools. The shelter exceeds all standard earthquake specs for buildings. Very cool idea and a very well done video. The objective was to find shelter for refugees rather than sticking them in tents. Adding Portland cement to the sand makes for a very permanent structure. In a nutshell, the construction technique uses a modified type of sandbag. The defensive advantages should be readily apparent. For someone with little money to spend and little time left, this could very well be a good solution. Architectural drawings are available if needed for building permits, etc.

JWR Replies: More about retreat architecture will be posted in the near future. But for now, here is a teaser — just as FFTAGFFR.
