The term Minimalism has not always been used in a favorable sense, especially in architecture, and even today it may be the cause of some confusion and ambiguity. The problem comes from the word's use in defining a creative current, school or trend when in fact it refers to an aesthetic. At the same time, this aesthetic is not chronologically well defined either and, moreover, interacts with different disciplines. This explains why we find minimalist buildings in periods very far apart from each other and in architects as different as Tadao Ando, Eduardo Souto de Moura, Jacques Herzog & Pierre de Meuron or Luis Barragan, among others.
