The new administrative headquarters of the Rhône-Alps region makes a bold statement in terms of urban construction and architecture: generous glass façades that reveal the interior of the spacious foyer and the open-plan meeting rooms form the counterpoint to the ceramic-covered fronts concealing the working areas. The particularly light natural hue of the profiled TERRART®-Large elements gives the massive superstructure a feeling of lightness, while the interplay between oblique lines and exact verticals reduces its severity. The corresponding TERRART® panels offer multiple cross-sections and have been specially manufactured and cut to size for this building. The substructure has also been specially modified to enable the unusual architectural concept to be realized.
