Informed by broad social assumptions, transport planning has traditionally obliged to the travel needs of the average (Vasconcellos, 2001; Levy, 2013b). In this process, children’s imaginaries and aspirations have been overlooked and dominated by an adult world were mobility is regarded as going from A to B efficiently. Challenging this view, this research considers children’s mobility as a practice that involves walking, playing and socialising, and the means by which children ‘perceive, feel and act in the world’ (Lester and Russell, 2010). Thus, it recognises that children’s everyday pedestrian practices matter, and that broader independence significantly contributes to their well-being and participation in urban life. Given the lack of attention to children’s independent mobility and play in the global south, this study analyses their impressions in a low-income neighbourhood in Cali, Colombia. Through a socio-ecological framework that incorporates the concepts of attachment and affordance, the study explores independent licence, walking perceptions and experiences, community ties and sociability. Findings suggest that in this context, independence is at constant negotiation between children, parents and household dynamics. In this sense, while children have high levels of independence for essential journeys, their freedom to roam, play and socialise is more restricted. Both road safety and the changing circumstances in the social environment, in terms of high levels crime and violence are crucial determinants in their participation in the neighbourhood. Policies should promote greater freedom and playability through strategies that facilitate rich social and physical affordances, and focus community engagement and appropriation of the street.

Opportunity to play can make a positive contribution across the life course. While successive amount of academic literature has shown how play can increase levels of physical and mental health for children, its ability of sustaining the quality of life into the older age has been dominated by a piecemeal age and gender specific approach (Mahdjoubi and Spencer, 2015). Action in actual urban design practice is still in infancy. This project addressed the gap. An extensive amount of liteature review demonstrated the rich potential of the older people’s opportunity to play in urban public realm and ‘active aging’ (WHO,2007) and ‘healthy aging’ (WHO, 2012). In order to encourage and respond to the innate needs of playfulness for older people more effectively, this project challenged the conventional approach- es to environmental design by introducing a more dynamic and richer typology of urban environment in forms of trails that can potentially encompass multiple play- ful elements.
