Organized complexity of the urban object

Abstract

Over a half-century, space syntax has proven resilient as a theory and method for describing and analyzing the built environment from dwellings and complex buildings to cities. The paper briefly discusses resilience as a concept in the built environment and the foundations of space syntax itself. We summarize the body of the theoretical thinking in space syntax – laws of the urban object, generic function, principles of centrality and linearity, the design method of spatio-formal processes, and laws of spatial emergence-convergence – before offering a new hypothesis about laws of spatial conservation and spatial optimization at work in the built environment. The latter builds on Conroy-Dalton’s (2001) ideas about angularity and the conservation of linearity in movement. Both could provide an essential bridge with Carvalho and Penn’s (2004) concept of self-similarity in settlements, which relates to Batty and Longley’s (1994) notions of fractal cities. We argue the hypothesis of conservation-optimization defines the conceptual framework for the progressive and regressive practice of urban planning in settlements. We illustrate this theoretical discussion by demonstrating the resilience or replication of previous space syntax findings, and by drawing on new research about the history, spatial structure, and neighborhood logic of Metropolitan Doha.
