In a second level, some of the activities not only need weather protection, but also some functional control that means that they can open or close according to their working times and the needs of each specific element. For this intent, we have designed small constructions as mini floating buildings with a tree leave shape. Modules can be grouped if the activity requires bigger space (cafeteria, kiosk, study areas, library…). We offer a catalogue from which citizens will chose during the project phase which ones they decide to be implemented in which places. Also, new modules and uses are very easy to be incorporated following the same design principles.
