Conceived specifically for the upper gallery, Luminous Territory (2007) is a rectangular structure that almost fills the space, orchestrating the routes of access around its enclosed perimeter. Here, Rackowe uses generic building materials: scaffolding and hoardings draw direct association to changing urban landscapes; the structure’s orange base references the colour of building works local to the artist’s house and studio; and the industrial sheeting that enwraps the work is common in construction. While the structure creates volumetric displacement within the gallery due to the dominance of its exterior surface, its interior activity is also clearly visible. Flickering light cast from the interior of Luminous Territory evokes the dysfunction of vast abandoned urban spaces. Although apparently random, the light is in fact carefully choreographed via dozens of fluorescent lights that flicker into life one by one, slowly animating the static structure.
