The Portuguese magazine Arqa published a “Vazio S/A Dossier” in its last issue (Jul-Aug 2011). Like the hugely popular Domus D’Autore by the Italian Domus, Arqa’s dossiers are a space open to a  guest architect/editor who, like in a magazine within the magazine, has total freedom to select content, texts, projects and graphic design. “Vazio S/A Dossier” was designed as a response to Arqa’s topic of this month – “South American Contrasts”.
