The space in-between, that one that is not in either of the buildings, probably the one created by the people leaving the flats, the same space that they left behind when changing to a new house, the one that looks empty but that is not empty at all, that is exhumed in the whole area, on the inside and outside... This is the reason why I chose to project in-between, and why I thought that a curtain is something that protects from the outside and that exposes the inside, so I took one that was left in one of the empty flats and I superimposed a projectection of both things on the inside and the outside of it.
