Cercas depicts a society under siege in which social order has collapsed or can only be imposed by the most drastic methods.
The images show the exterior of buildings, the protective fences and walls that surround them, the private urban prisons built in the most opulent districts of some cities. The photos afford a fascinating vision of how some people live, in what seems like a besieged existence in a kind of self-imposed, protective custody.
The absence of life in these images of heavily protected houses makes them more dramatic and unsettling, and the more we look at them the more we realise that there is nobody, absolutely nobody, at home.
