(available in portuguese, spanish, english and french)

A former UN worker and prominent architect, Johan van Lengen 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 (earth, bamboo, as well as some conventional materials), and application. 

The author emphasizes throughout the book what is inexpensive and sustainable.

Included are sections discussing urban planning, small-scale energy production, cleaning and storing drinking water, and dealing with septic waste, while all information is applied to three distinct tropical regions: humid and temporate areas or desert climates.

Hundreds of explanatory drawings by van Lengen allow even novice builders to get started.
