The invention discloses a beam-free light container house with the adjustable area and shape. The substance-field analysis method of the TRIZ theory is applied, the column structure, the beam structure and the plate structure of an existing light container house are subjected to force analysis, and the feasibility of clipping beams and the applied technological approaches of the clipping beams are revealed; on the premise that the safety and the comfort are guaranteed, flexible control shapes (the square, the rectangle, the pentagon, the hexagon, the circle and the like) are achieved, and the using area is larger than or equal to 9.6 m<2>; multiple-specification size houses are achieved, the technical effects of self-assembling, self-disassembling and rapid disassembling and assembling can be achieved, and a new selection is provided for development of the container house.
