A method for producing a sustainable building without the use of heavy equipment. Such a building may include an adjustable foundation to eliminate the need to flatten the building surface below. The frame may be constructed by using hand tools to assemble pre-rolled galvanized steel rods. A pre-cut perforated galvanized steel sheet can then be laid on the frame and sheathed with a pre-mixed mortar that may be created by mixing materials easily found in impoverished countries, such as natural lime, river sand, white clay, and fly ash. The roof may be layered with a thin solar film to allow for the incorporation of solar cells to harness solar energy and may further include a rainwater collection mechanism to allow for the roof to also collect clean rainwater.
