The moving part appears as a volume containing in its interior
a functional space including all the elements
of a traditional part being able to be moved on demand.
Sliding to a rail integrated in the ground,
volume can shift on a simple gesture.
In closed position, against the wall, volume
contains the whole part and thus occupies a restricted space.
In opened position, volume rolls out along
the rail and gives access to the part while shifting laterally
from the wall.
