Now, designers have planned dome homes, tents, personal mini-domes and fantastical structures that serve as beautiful homes, that save up to seventy percent on heating and cooling and that can withstand many “Acts of God.” While domes have their opponents, their objections - more often than not - have been overturned. Building codes, sound problems, privacy and weatherproofing all have been resolved through compromise, extensions, building in levels, and building with new materials. This type of home uses less material and labor and are suited to mass production.

Domes are not ecological, because they are incompatible with an urban setting, which has the smaller carbon footprint per person.
