This chapter focuses on how an arts-based civic participation process can allow the voices of young people to be heard. Urban development in Finland is regulated with laws, norms and rules based on institutionalized democratic decision making, which means that processes are protracted. Two years is not a long time in a planning process, but it can be a very long time for young people distanced from the language and practices that shape civic discourses. The reality is that young people aged 18–29 are often a neglected group in Finnish municipal decision-making. Their voices and perspectives are not being heard, especially those most vulnerable who are not in education, employment or training. A different type of approach could allow young people’s ideas to be included in planning processes, by creating the conditions through which they can gain agency in the development of the area in which they live. This chapter explores how this can be achieved through a process of learning, focused on imagining alternative futures based on social justice in which young people are valued and have a stake. To address this, we open-up for investigation ‘The Disimagination Machine’, a process we as researchers and practitioners created using pretext drama, situated in the fields of Applied Theatre and Critical Pedagogy.
