The exhibition structure is composed of five layers of cardboard panels, stacked to form walls, which loosely follow the outline of the exhibition space.
The panels change in height and fold in different directions to the ones above and below; they are all flat but not generally vertical.The folded arrangement creates steps and 'shelves'on which the designers'models are positioned.
The overall stability of the structure is achieved by the folding geometry of the walls and by overlapping the panels, so that, for example, the folded portion of an upper panel is triangulated with the straight portion of the panel below it and vice versa.
The panels are of 30mm-thick honeycomb cardboard, faced both sides with aluminium foil to give resistance to spread of flame; they have a thin white paper finish. The panels are structural.The top edges of the upper panels are hung from an existing ceiling track with a ring and hook connection; the bottom panels are held in position by screw-fixing them to the groundfloor slab.
Folds at panel junctions are made with 50mm-wide brass hinges screw-fixed to paneledge battens; the joint is reinforced with white card angles, which were glue-fixed on site, giving rigidity to each layer of panels.
The design was developed by means of a computer modelling tool, which dimensioned and defined the angles of all the cardboard panels; they were then pre-cut to the correct shapes and delivered to site as flat panels.Once on site the lower band of folding wall panels and all full-height panels were installed and supported from the ceiling.For stiffening, a 50 x 29mm softwood batten was glue-fixed to the top edge of a panel on which an upper band of panels would rest.
