The Barefoot Architect
Written by former UN worker and prominent architect, Johan van Lengen who has seen firsthand the desperate need for a "greener" approach to housing in impoverished tropical climates.
This comprehensive book clearly explains every aspect of this endeavor, including design (siting, orientation, climate consideration), materials (sisal, cactus, bamboo, earth), and implementation.
The author emphasizes throughout the book what is inexpensive and sustainable.
Hundreds of explanatory drawings by van Lengen allow even novice builders to get started.
