This paper involves an exploration of how architecture, landscape and construction spaces contribute in urban design by providing incentives for interaction and emergence of collaborative ventures during a large cultural development initiative. The paper contains an analysis of how spaces becomes boundary mechanisms facilitating the translation of a cultural vision. By elaborating on ‘boundary spaces’ to explain the materialization of an urban strategy we use a praxeological outlook as it is framed in the strategy-as-practice literature. When we more closely delves into how spaces can be set in motion and become generative platforms we use the notion of action nets. Methodologically, the paper investigates how such strivings are articulated, planned and implemented in a local context by using a narrative approach comprised by analyses of narrative infrastructures. By mediating different layers of interpretation, boundary spaces turn into artifacts exceeding strategic projections.
