A scaffolding module for multi-level building scaffolding, comprising; a frame that, when in an erected configuration, defines an interior space configured to receive workers, said frame being formed from a plurality of frame members (13, 15); and a plurality of mounting regions that allow the module to be mounted with other said scaffolding modules, the mounting regions being disposed on (i) upper and lower faces of the frame so that the module may be mounted with other said modules one on top of the other to form multiple levels of the scaffolding and (ii) on opposite side faces of the frame so that the module may be mounted with other said modules in side by side relation; characterised in that at least one scaffolding platform section disposed in and supported by the frame, and in that, when arranged to be mounted in side by side relation, the opposite side faces having openings to allow the workers to freely pass to another said module; and at least some of the frame members (13, 15) are formed from profiled sections and at least some of the mounting regions are configured as surfaces of the profiled sections and which are arranged to abut in face to face relation with a corresponding mounting region of another said module, the frame members (13, 15) are interconnected by rigid connections and the profiled sections include pre-formed holes to receive mechanical fasteners to secure respective profiled sections together when the module is secured with another module, and when so secured, the profiled sections are in intimate contact and act effectively as a unitary structure that enhances the rigidity of the mounted modules. a frame that, when in an erected configuration, defines an interior space configured to receive workers, said frame being formed from a plurality of frame members (13, 15); and a plurality of mounting regions that allow the module to be mounted with other said scaffolding modules, the mounting regions being disposed on (i) upper and lower faces of the frame so that the module may be mounted with other said modules one on top of the other to form multiple levels of the scaffolding and (ii) on opposite side faces of the frame so that the module may be mounted with other said modules in side by side relation; (i) upper and lower faces of the frame so that the module may be mounted with other said modules one on top of the other to form multiple levels of the scaffolding and (ii) on opposite side faces of the frame so that the module may be mounted with other said modules in side by side relation; characterised in that at least one scaffolding platform section disposed in and supported by the frame, and in that, when arranged to be mounted in side by side relation, the opposite side faces having openings to allow the workers to freely pass to another said module; and at least some of the frame members (13, 15) are formed from profiled sections and at least some of the mounting regions are configured as surfaces of the profiled sections and which are arranged to abut in face to face relation with a corresponding mounting region of another said module, the frame members (13, 15) are interconnected by rigid connections and the profiled sections include pre-formed holes to receive mechanical fasteners to secure respective profiled sections together when the module is secured with another module, and when so secured, the profiled sections are in intimate contact and act effectively as a unitary structure that enhances the rigidity of the mounted modules.
