A folded structure transportable to a desired site for erecting a building structure adapted to include a member having a width selected from the group consisting of a door assembly and a window assembly, the folded structure comprising: a fixed space portion defined by a first floor component, a first ceiling component, a first wall component having a horizontal length and two vertical edges, a fixed portion (200b-1) of a short wall component, and a pivoting portion (200b-2) of the short wall component pivotally attach about a vertical axis to the fixed portion of the short wall component, the first wall component comprising: a floor plate defining the lower longitudinal edge of the first wall component and spanning the horizontal length of the first wall component; a spanning beam defining the upper longitudinal edge of the first wall component, said spanning beam positioned above the floor plate and spanning the horizontal length of the first wall component, the spanning beam adapted to carry structural weights and loads received from the ceiling of the building and any additional floors; a first structural column assembly and a second structural column assembly, the first and second structural column assemblies positioned between the spanning beam and the floor plate and structured to carry structural weights and loads received from the spanning beam; the first and second structural column assemblies inset from the vertical edges and separated by a longitudinal distance to define an intercolumnar region, the width of the intercolumnar region being greater than the width of the member; and an exterior panel fastened between the first and second structural column assemblies to define a generally continuous and uninterrupted planar surface over the intercolumnar region; the folded structure further comprising: a second ceiling component horizontally stacked on the first ceiling component; a third ceiling component horizontally stacked on the second ceiling component; a second wall component vertically positioned against the pivoting portion of the short wall component (200b-2); a second floor component vertically positioned against the second wall component; and means for pivotally connecting, about a horizontal axis, the second ceiling component to the first ceiling component, means for pivotally connecting, about a horizontal axis, the second floor component to the first floor component, and means for pivotally connecting, about a horizontal axis, the second wall component to the second floor component. a floor plate defining the lower longitudinal edge of the first wall component and spanning the horizontal length of the first wall component;
