The volume is a massive piece by contrast rises and is projected as metaphore of freedom. The building has been designed as a sculptural connotation to surprise and show a different image depending on where it is appreciated. The building is composed of a double skin, the first solid and blind in contrast to the second light and transparent. The blinded skin (or buried skin) is the skin that is required and according to the program it belongs to public spaces, and the translucent skin (paradoxically) belong to the private spaces; transparency sensations, vertigo and weight simultaneously coexist.
