A new image for an industrial mechanic factory was comissioned. We agreed to use the material employed in the factory to create the new image and reuse the scrap metal from the same. Our intention was to design a repeated easy material piece to obtain from the scrap of their daily jobs. Therefore we design a pannel of 59 x 59 cm of steel plate and played with the position of these. The location and distance between them is calculated according to sunlight and airflow to provide a pleasent external promenade and a shadow-light effect to enfacice the factory from the passing road.
