The Versadome is a modular building system based on three organic shaped rigid structural shells in the nature of arches and domes. All components are designed to stack for easy transportation and assembly. Four complete units (approx. 800 square feet of enclosed space) can be stacked and transported in one standard shipping container. I really like the idea of it being stackable and easily transported. Would be quite effective in reducing the transportation energy of a building. Not too sure about the material its made of though.
