Letter Re: The Afghan Walled Courtyard Design for Retreat Architecture

My daily internet traipsing brought me across a photoset of Afghan walled compounds.

It seems that the basic unit of Afghan country life is the extended family, all of whom live within a 12 foot walled compound. Since Afghanistan has lacked real sovereignty for centuries, this seems to be the logical endpoint of the evolution of retreat/farms. Note that they are not unlike the early spanish missions in the American Southwest. – Isaac R.
