City of icebergs: materiality, surface and depth in Nairobi’s built environment

Abstract This article considers the materiality and substance of the built environment in Nairobi in light of concerns about surface, depth and the power of the unseen. Taking Nairobi’s high-rise construction boom and a recent spate of collapsed buildings as its starting point, it examines how longstanding ideas about the hidden and invisible dynamics of African cities do not operate in a realm distinct from the material world, but often stem from it: the stuff from which the city is made generates thought and action. High-rise buildings are sometimes described as ‘icebergs’ (structures where much of what is going on is under the surface) or as ‘fakes’ (buildings that superficially promise something, but that are qualitatively and morally suspect). Exploring Nairobi’s construction industry from sites of building collapse, I show how an emerging vertical materiality in the city’s built environment drives debates about deception, (im)moral economies and popular suspicions of power, complicating discourses about the relationship of surface to underneath. I examine how Nairobi’s frail buildings induce anxieties about the seen and the unseen, illuminating how the materials of verticality are entangled in economies of deception.
