Popularized by the great inventor R. Buckminster Fuller in the 1940s, a geodesic dome is a half spherical structure made up of many smaller triangles that uses the same building blocks as nature to create structures that encompass the maximum amount of space with the least amount of materials-and all while being remarkably strong! They have been used as temporary health clinics, classrooms, military installations, shelters, greenhouses, tool sheds, portable homes, glamping structures, and much more.
