"Notes on the synthesis of form" by Christopher Alexander is a wonderfull book, and including several Marvin Minsky quotes it can be read as an introduction to the philosophy of vernacular technology - and how tradition based design work differs from expert, intent and theory driven design. Vernacular technology has it's problems, but as long as the problem constraints are not changed, it works wonderfully in the environment that gave birth to it.

For more northernly latitudes, there's the sod roofs, sod houses (https://en.wikipedia.org/wiki/Sod_house) and icelandic turf houses (https://en.wikipedia.org/wiki/Icelandic_turf_house).

I have heard about this book "Notes on the synthesis of form", will check it out.

There is profound depth in African culture, including the craft and symbology in the architecture.

May I recommend the beautiful series The Tribal Eye, BBC, 1975, presented by a strapping young David Attenborough in his 50s?
