Friedman looked for ways and methods to give the individual as much influence to achieve an environment and a way of life as one sees fit, not disturbing others and not exhausting the environment. His first projects were designed for large-scale simple, inexpensive and often temporary shelters to realize using existing prefabricated materials.

Example of the construction of domes as a simple technology easy to apply by future inhabitants, Yona Friedman, 1970-1975
Later his ideas for simple technology focused more on the empowerment of people in difficult circumstances, like shanty towns. Also he promoted the use of simple technology to give people tools and ideas how to create their own space and facilities.
