This two-floor apartment is located in a late 19th century’s traditional building typology in Milan, the “casa di ringhiera”, which used to be a social housing with aligned flats with shared balconies. The owner is a young informatics professional with a fervent passion for extreme sports and his Harley-Davidson motorbike. The concept of this design project reminds me of a famous 80s hard rock song: AC/DC’s “Back in black”. The steel structure of the ceilings has been revealed to recall industrial aesthetic. The opaque black of the Harley-Davidson runs along all the ambients and underlines the main design interventions. Back-painted black glasses, sharp light effects, dark concrete-like resin and rhomboid mosaics reproducing metal nets shapes contribute to create a garage-like aesthetic. This rocker attitude contrasts with the domestic warmth provided by the diffuse use of wood for furniture and flooring.
