“Eco-dome Morocco is an ambition that draws both in the basic design of the American-Iranian architect Nader Khalili and the rich Moroccan heritage in earth-based construction. This perfect combination is our main source of inspiration to give our buildings a new architectural and structural sense: buildings that respect the environment, adapt to the environment but mostly emanate from the environment; And because it is believed that human comfort lies in its return to nature, Eco-dôme Maroc is there to ensure this first step.”
Cost: The square meter cost is 45% less than reinforced concrete.
Rapid construction: Construction time is 50% less than conventional construction.
Strength: Stable and weatherproof structure.
Emissions: Reduces CO2 emissions by up to 64%.
This design eliminates the rather difficult part of building the top of the dome. Plus, it looks really cool to me. Other people have built this way also such as a couple in Canada: http://www.naturalbuildingblog.com/update-on-canadian-dirtbags-earthbag-home/
