While the entrepreneurialisation of local administrations is widely acknowledged, the extent and format of institutional and organisational structures that accompany market-oriented ideological shifts and transitions in urban governance often remain unnoticed. This article provides an original theoretical argument and frame of analysis to forensically study the underlying infrastructures of entrepreneurial governance systems. We argue that complex institutional and organisational arrangements in market-oriented urban development can be comprehended through fragmented governance architectures, a conceptual perspective that we borrowed from governance studies and operationalised in relation to property development. We illustrate the application of the framework by examining entrepreneurial transformations in Amsterdam’s residential property production. Based on rich empirical evidence, including discourse analysis, policy analysis and in-depth interviews with key policy and property industry actors, we illuminate divergent public-sector regulation of market activities, intra-organisational discrepancies, and fuzzy narratives in policy interventions which are tied to specific spatial interventions mushrooming in the city. Uncoordinated and sometimes contradictory institutional ties link public and private actors in these property production processes, forming a complex and chaotic landscape of regulations, actors, and relations. This fragmentation, we posit, warrants recognition as it lies at the heart of scattered investments in the urban built environment.
