Public spaces are usually designed to be vibrant and socially engaging. This thesis considers the alternative: creating spaces designed for Solitude in public realm, as a critique and expansion of the conventional understanding and repertoire of public spaces in the city. From a sociological and psychological perspective, Solitude offers precious freedom. In crowded density, it allows one to disengage from the demands of others: a restorative freedom from social constraints. A depth of connections and levels of engagement, beyond direct interaction. This form of Solitude found in urban density, exists together with the vibrant public space, where the individual is connected but not burdened to participate. On the human scale, the thesis investigates the environmental and somatic conditions necessary to create Solitude. On the urban scale, a prototype “generic city” is formed as a testbed for the hypothesis. From an understanding of the typical urban fabric, behavioural commonalities and temporal patterns that comprise the complex lattice of the city, frameworks are developed to extract potential urban conditions. Subsequently, analysis and designing of the architectural responses to bring out Solitude. Mindful of the highly contested nature of public space, the thesis seeks a means of tactically weaving these spaces into the urban realm. A dual-nature comprising a concerted effort on the scale of a city, yet inherently operating on the intimate, human scale. The thesis thus proposes the conception of a Positive Urban Solitude, a Solitude that exists embedded and connected to the public realm, mediated by architecture.
