“Avalle has known how to maximize, each and every time, transparency and luminosity, relative softness and the possibility of opacification, colorability and refraction utilizing the new material not only as a substitute for glass, but as a volume and stratified surface capable of withholding and reverberating chromaticisms, internal structures, linear and figural marks”. (V. Fagone, Avalle – Architetture di Luce, ed. Valente Artecontemporanea 2002)
