The building that B01 Architects built for Carburos Metálicos in Barcelona's Carrer d'Aragó, and some of the works of Catalan architects Tous i Fargas, illustrate the need, at that time, of developing industrialized construction systems for the blind area of the facade. The aim was to build a blind façade with a technology similar to that used by the glass and aluminium industry for glazed envelopes.
