The tragedy of the commons underscores that when individuals access shared public resources, they often act in self-interest, leading to resource depletion and degradation. This phenomenon is exacerbated by the sense of detachment inherent to non-places, such as fast-food restaurants, waiting rooms, or shopping malls, which are characteristic of supermodernity. While research has extensively explored the positive influence of place attachment, the drivers of negative behaviors in non-places remain insufficiently understood. This study addresses this gap by investigating the mechanisms underlying inconsiderate behaviors in non-places and exploring how these spaces can be reimagined to encourage pro-environmental and pro-social behaviors. Grounded in the Norm Activation Model (NAM) and the Theory of Planned Behaviour (TPB), we identify six Design Requirements from existing literature to guide our analysis. Employing a Design Science Research (DSR) methodology, we then propose four actionable Design Principles aimed at enabling innovators, including managers and entrepreneurs, to foster sustainability in non-places. Our findings provide novel insights into the spatial production of sustainability and offer a practical framework for promoting considerate behaviors. This work contributes to the intersection of spatial design, social innovation in and of urban spaces, and sustainability, equipping practitioners with tools to transform non-places into environments that encourage collective well-being and responsible resource use.
