This research, is an investigation on how to redefine an in-between boundary by creating new spaces and new meanings. In this case, I redefined the role of an in-between wall inside a house, using it to reveal instead of divide and hide. The space is redefined here from transparent and opaque blisters, that go from one room to the other through the wall, creating shelves and storage spaces. Since what you store on the blisters will be visible also from the other side of the wall, the level of transparency of the blisters will define the typology of objects you place on them.
