The top level is 3.5 metres above sea level. The next level is at 1.4 metres above sea level and hosts the daylight zone with all services and allowing outdoor access. The third level is situated at 0.8 metre below sea level, semi-submerged, and is devoted to the night-time zone. At 3.0 metres below sea level, totally submerged, there is the underwater observation bulb, an intimate and mediative place.
