The principle of the design is mainly based on a shell made from perforated metal sheet. The perforated pannels creates a play of light and shadow, and the diameter of the holes can mixt to create diverse patterns. The dark metal pannles constrast with the brass metal pannels of the vertical elements. The facade is subdivided in to a grid defined by the vertical elements and the height of each level. The grid is placed with the other pre-existing elements on the facade like the concrete casing and sill. In front of the windows we have 4 identical perforated pannels that act like a shadding device. Each pannel can be opened by the inhabitants. They can either leave them opened to get more light, or close them so they would have shade and more intimacy. The movement of the shadding pannels create a dynamic facade. The materials , colours and the perforated shell gives the facade a contemporary look.
