The selection of the structural material is made according to fire code requirements or economic conditions. A red enameled steel envelope covers every part of the structural frame. It is designed so as to solve every interior or exterior corner, cantilever or edge condition. Although the Folies proceed from a simple construction principle, deviation alters the relationship to the structural grid. The grid then becomes a simple support around which a transgressive architecture can develop in relation to the original norm.
Deviation is both the excess of rationality and irrationality.
As a norm, it contains the components of its own explosion. As a deviation, it frees them.
