The American Bar in Vienna, designed in the early twentieth century by the architect Adolf Loos, condensed the designer’s obsessions with natural stone and decoration into just 27 square meters. A precious and inclusive architecture that, in the dualism between inside and outside, proposed new uses and customs for inhabiting space. Like an alchemical mixture between scenography and monument, we imagined reconstructing in parts the warm and welcoming atmosphere of the “Marble Bar”, a provisional name that appears in Loos’ first sketches. In a representation that is not authentic but faithful to the original, Marimar made use of new techniques to update the formal catalog of the project by making the onyx thin and transparent like a veil, pretending slabs in the form of monolithic columns and combining textures and processes capable of trigger new surface values.
