Knowle West Media Centre (KWMC) believes that all people, whatever their background, should be able to imagine, co-design and shape their future, for themselves and their community. KWMC uses an arts-led Co-Creation process that generates creative, engaging and relevant ways for people to get involved in activism, education, employment and local decision making, leading to and building networks, communities of interest, and strategic interventions that can contribute to wider system changes. The chapter outlines this approach, which builds on participatory research practices and the concept and practice of ‘common-ing’, and how this approach can be applied to diverse settings, issues, and engage diverse participants. It shares two case studies: The Bristol Approach to Citizen Sensing which develops an alternative people-first approach to Smart Cities, Big Data and new technology; and We Can Make, which takes an asset-based approach to citizen-led housing and enables housing to be developed at ‘point of need’ by unlocking micro-sites for development. Over twenty years KWMC’s approach has achieved significant impacts at the individual and collective level. However, there remains a challenge to secure fuller recognition and engagement from decision-makers and a commensurate shift in resources and power relations that would enable more people to work together effectively and non-hierarchically towards the change they want to bring about in their communities.
