Patent number: 10196809Abstract: The invention is a modular building component with rod-based dimensions. The modular building component comprises a prismatic box structure. A number of the prismatic box structures are placed side by side horizontally to create a ceiling and a floor with rod-based dimensions. The ceiling and the floor function as components of a building with rod-based dimensions. The building may also have walls that are also prismatic box structures with rod-based dimensions. Two or more of the buildings can be placed side by side to fill equal portions of an entire width of a perfect-acre lot. The buildings that fill an entire perfect-acre lot lead to a sustainable community design, given that no space is wasted. The rod-based building components are properly dimensioned for quickly assembling these optimally sustainable buildings.Type: GrantFiled: June 13, 2017Date of Patent: February 5, 2019Assignee: Hall Labs LLCInventors: David R. Hall, Benjamin Jensen, David Lundgreen, Joe Fox
