A demountable structure system is disclosed. The demountable structure system may have a roof system positioned atop one or more structural panel(s) and a floor system positioned beneath one or more structural panels(s). The structural panels may have different shapes, configurations, and features, and may support the roof system in order to form a demountable structure. Alternatively, the roof system is omitted and a wall or other structure can be formed from the structural panels. Each structural panel may have other features, such as finish panels, fabric panels, accessory mounts, recessed lighting, electrical outlets, etc. Some structural panels have sound dampening features, such as to form portable musician's sound booth. Thus, a structure may be formed which is both readily disassembled, yet also sturdy.

The invention relates to a roof forming element for a roof, comprising a roof plate, a beam integral with the roof plate, such that the integral combination of the roof plate and the beam has an L-shaped cross-section, a cover, and coupling means for coupling the roof forming element to a further, neighbouring element. The roof forming element, at least in a mounted condition of a plurality of such elements, is configured such that the second longitudinal side of the element is arranged to be supported by the first longitudinal side of a further, neighbouring one of said elements, so that the beam of the further roof forming element also supports the roof plate of the roof forming element, and so that the respective roof plate elements of said roof forming element and further roof forming element are flush with respect to each other.
