Lara Almarcegui is a conceptual artist whose work touches on building materials and their eventual dereliction. Both subjects are tied to Almarcegui’s interest in processes of urban transformation brought about by political, social, and economic change—ideas that she began to study sedulously in the mid-1990s. “Wastelands are important,” Almarcegui says, “because they are the only places in the city that remain without definition.” In some projects, she bundles the information she gathers into “guides”, about the past, present, and future of specific lots. In others, she presents installations of construction materials in ordered piles, or in mountainous heaps. For a Frieze Art Fair project in 2006, Almarcegui made a work consisting of the exact materials and their quantities used to construct the Fair’s tent.
