After the fall of the Fascist regime and its defeat in World War II, Libera along with everyone else underwent a period of personal and professional crisis, but after living quietly for several years in his home town of Trento, he recovered and began again to work on numerous projects, including public housing and office buildings, in a new style that turned its back on Fascistic modes of expression.
Despois da caída do réxime coa súa derrota na Segunda Guerra Mundial, Libera xunto con todos os demais pasou por un período de crise persoal e profesional, pero logo de vivir tranquilamente durante varios anos na sía cidade natal de Trento, recuperouse e empezou outra vez a traballar en numerosos proxectos, incluíndo edificios oficiais e vivendas públicas nun estilo novo que daba as costas aos modelos de expresión fascistas.
