Thin-shelled concrete roofing

Thin-shell concrete roofs and shelters were originally designed by Dr. Albert Knott and Dr. George Nez as a solution to providing quality, low cost shelters to people displaced by poverty, war, and disaster, and also as an affordable alternative for high quality roofing. 

Thin-shell structures are extremely low-cost, can be made with materials local to most places around the globe, can be quickly and easily constructed by unskilled labor and hand tools, and require little to no maintenance.  Learn more by clicking on the presentation link to the right.
