This thesis examines the potential of non-statutory interventions for enhancing community well-being, emphasizing participatory research methodologies that focus on community strengths and resources aligned with their concerns and needs. The research specifically investigates the well-being benefits of engaging with a community boxing gym for young individuals residing in a diverse area of Inner London. Part one of the portfolio explores the use of Participatory Action Research (PAR) with people experiencing homelessness (PEH) in the U.K. and Ireland. This is a scoping review of current literature and includes recommendations for those wishing to use PAR with PEH.  Part two presents an empirical study utilizing ethnographic research methodologies to gain a community perspective on the well-being benefits of boxing for young people. The findings indicate that boxing, as a community activity, offers associated well-being benefits that young people willingly engage with, particularly those who face challenges in accessing statutory services. Engaging in boxing at a community gym fosters a shift in sense of self, linked to a recursive learning process and a sense of belonging to a "new family." These elements can be directly linked to improvements in well-being.
