The design makes visible the three elements of the townscape of Meyrin: freestanding building slabs in generous parks and wide streets. The linearly organized, stepped city hall shows and follows the original urban conception of Addor and pay reference to his ideas. The horizontally structured north façade facing the square shows the entrances, the administration and, at the top, a rigidly greened winter garden. The stepped south side is also horizontally structured with a courtyard and open terraces.
