A centralized fluids network (water, gas, electricity and evacuations) makes this equipment able to work in open or closed position.

Perfectly equipped, the part is thus quite as functional as a traditional part, with the advantage of being mobile. For example, the kitchen units (the sink and electric household appliances) are usable permanently: the part can thus be moved constantly, even during its operation. The concept thus allows a true space saving and a total interior modularity : the space occupied by the open part remains available for any other use once closed.
