We have developed a revolutionary patent-pending construction system founded on the principles of the circular economy. It combines cutting-edge digital and distributed manufacturing techniques with the simplicity of a children's toy, to allow construction at 5 times the speed of traditional methods and mastery of the construction process to be attained within days. It allows the assembly, disassembly, and reassembly of buildings many times, in many configurations, for many purposes - all without generating waste - and therefore opens up new possibilities for construction.
