The promise of a strong design: like a tightly locked safe: the building, with an even structure, has finely chiselled and equipped earthen cladding. “A marvellous object”, it offers a “strong design”, a protector, symbolising sustainability and stability as the primary goal of the institution. The perfectly square building receives different light depending on the side, whilst presenting a standard material. It encourages “guessing” with pure and precise architecture – which the archives retain and protect. The archives are a symbol of sustainable and visible development for the memory of Haut-Garonne residents.
