Low 4 unit
umbrella + earth and reeds box = economical house

Solution

The conception of the 300$ house is made by prefabricated
earth and reed pannels.
The main idea is to industrialize this concept and to use it
in slums at a large scale. Doing this permit to reduce the
construction cost.
The umbrella should be done by materials already use on
the existing slum house�s (reed or wood).
Multiple challenges :
- use local labour to promote the local economy
- make this project easy transportable with an easy
handling to facilitate the site access and avoid big machine
use.
