This case study describes the "Reimagining Door 84" project, a participatory ethnographic research initiative conducted in collaboration with Door 84, a local youth and community center in York. Researchers from York St John University collaborated with young people, empowering them to design and implement their own research projects. Using methods such as surveys, interviews, and mapping exercises, the young researchers explored community relations and envisioned future possibilities for Door 84. Central to this project was the emphasis on ethical cocreation and genuine collaboration, fostering an inclusive environment where youth autonomy and agency were prioritized. The case highlights the dynamic nature of informed consent, illustrating how trust building through "deep hanging out" allowed participants to engage and disengage on their own terms. This fluid participation not only respected the young researchers' autonomy but also enriched the research process, leading to more authentic and meaningful contributions. Insights from this project extend beyond Door 84, offering a broader understanding of effective participatory ethnographic research with young people. Reflecting on the project's challenges and successes, readers will learn about the importance of flexibility, ethical engagement, and responsiveness in research. The case demonstrates the potential of participatory ethnographic research to engage positively with communities, guided by social justice and ethical principles, empowering young voices and ensuring their perspectives are represented in community narratives.
