All rooms are defined by the walls that they are enveloped by. At the same time, another space is shaped on the other side of these walls. In some cases these spaces are merely 'negative spaces', not constructed to be seen, much less to be photographed.
To explore these spaces and then photograph them was in a way much like an old expedition to remote and unknown territories, located just one wall away from the spaces that we are familiar with. By publishing these photographs (the representation of) those spaces are added to the notion of the visitor and thus alters the perception of that space when visited.
After having photographed the hidden spaces of several buildings in Chicago, the Chicago based company US Equities generously offered me the opportunity to work out the theme as a visiting artist. The book 'One Wall Away, Chicago' Hidden Spaces' was published in 2007.
