Interlocking elements (10, 20) are formed by two side panels (16) spaced apart in parallel face-to-face alignment sandwiching two protruding elongated elements (13, 15) spaced apart in planar alignment forming a slot (11, 21) therebetween. A series of interlocking elements (10, 20) stacked vertically in an alternating orthogonal array interlock with slots intersecting adjacent slots and panels to form a vertical structural support (figs. 5, 7, 12). In a preferred embodiment, the space between elongated elements is equal to the width of one elongated element. Each protrusion of each elongated element creates a tenon insertable in each mortice between elongated elements to form a coplanar vertical structural support. Alternately, second modular elements are formed with two spaced parallel side panels sandwiching a single elongated element protruding above and below the side panels. Horizontal slots are formed between side panels. First horizontal elements formed of a rigid member slide into horizontal slots and edge slots engage side panels to lock them in. Second horizontal elements are formed by spaced apart planar aligned planks interconnected by a shorter plank leaving a slot at each end to engage orthogonally stacked elements. Members (80) interconnect vertical structural supports. An adjustable brace element (122) connects between the top and bottom of the structure.
