We were called to reshape the lobby for a medical office. Our idea was to create an open space where the sun rays pass through to light up the otherwise artificially illuminated hallway. Compositionally it was decided to resume the comfortable patterns of dwelling. The sitting elements are not put in a continuity session, but are scattered here and there in accordance with the proxemics theories in order to create specific personal spaces, avoiding aseptic feeling of an anonymous space. Rather light colors, materials with soft natural texture, and comfortable volumes were chosen to create a peaceful and informal ambiance.
