This chapter delves into the nuanced relationship between the built environment and the health-oriented behaviour of its users, presenting a novel perspective by extending beyond the conventional focus on physical health to include mental health as well. Unlike previous studies that predominantly explored the physical health implications of the built environment, our research uncovers a broader phenomenon that integrates both psychological and social aspects of behaviour within such environments. By employing a scoping review method, we analysed documented research from the past decade across various digital databases. Our major contribution to the field is the development and validation of a hypothetical model aimed at promoting healthy lifestyles within the built environment. This model is underpinned by our findings, which highlight the complexity of health-seeking behaviour as it intersects with the psychological and social dimensions of individuals’ interactions with their surroundings. In the concluding section of the chapter, we articulate various domains of health-oriented behaviour in relation to the built environment and propose recommendations for qualitative transformations and design interventions. These suggestions are geared towards fostering environments that not only support physical well-being but also enhance mental health, thereby contributing significantly to the discourse on creating more holistic, health-promoting built environments.
