Abstract

Introduction: This paper presents a theoretical framework that helps identify visual sustainability in urban projects and evaluates its relevance for the use, design and making of public space. Aim: It is aimed at showing how the process of urban regeneration is far more nuanced and sophisticated than much of today’s building industry allows for. Methodology: The first part of the article provides an outline of this framework, by drawing from the notion of ambiguity and discussing regeneration around a concept of trojans of ambiguity: by which we simply mean that modern-day regeneration projects are often a confusion of meaning. The framework is then applied to two case studies: Heygate and Sidewalk Labs Toronto. Findings: The Heygate regeneration produced a negative emotionally charged process and social displacement. By contrast Sidewalk Labs Toronto exemplifies a technologically clean start for regeneration, on a site with little social vitality or history. The starting points for each ultimately point to two very different outcomes. Recommendations for further research: Visual sustainability represents ‘the technology before the technology’ and future research must recognise how human needs, not technology, provide the meaning into ‘how’ we may create a successful, smart, and sustainable urban.
