In Hormuz Iran, ZAV Architects worked on this project to develop beautiful and affordable architecture using mostly local materials. These dome clusters were built using the superadobe method, championed by Iranian-born architect, Nadir Khalili, where long tubes are filled with dirt and stacked to build walls. The vibrant colors they used throughout the project certainly make it visually pleasing and easy on the eyes. The small size of these domes would make them share many of the same benefits as a tiny house–including being easy to heat and cool, and round and dome-shaped walls have less outer surface area, another efficiency factor.
Creative and imaginative projects such as this are inspiring because they give one an intimation of how many variations of dwellings are actually possible. I can speak from experience that living in round structures has a special feel to it. If you think about it, our species didn’t evolve in environments with 90 degree angles everywhere. Organically-curved structures just feel more instinctively natural to us.
I have attached an article on the subject with a caveat, for those who don’t know, you generally don’t want to put straw or organic material in earthbags or superadobe tubes. In environments with any relative humidity, it would eventually rot away and probably harbor mold in the meantime, possibly harming the health of those dwelling within.
