Since early 1990's, the work by Rio Grande do Sul-born, São Paulo-based Lucia Koch has interacted with architecture as she modifies ambient lighting to cause noticeable changes in spatial perception. This, however, is not an intervention project. At Galeria Nara Roesler's conventional address in São Paulo, the artist Lucia Koch will present previously unseen works which reintroduce the materials she has used in her interventions in the last ten years, arranged on industrialized stands and "catalogued" by pattern and type of material. Each set/portfolio is a self-contained piece with many possible configurations, which viewers can rearrange by moving the panels around. Materiais de construção show begins at the gallery window and ends in the exhibition room.
