A facade entirely restored, blue, whose smooth aspect is reinforced by crates set back, potentially artistic. Clear intention of playing on horizontality. Two ways of giving stature to a building full of international organisations; of marking its presence at one of the gateways to the city; of symbolising discreetly the internationality of Geneva. An exemplary worksite, besides, through the low impact on its users who have no need to move out during the renovation work.
