Workshops provide a flexible approach to studying complex issues. This paper discusses the methodological considerations involved in doing research through workshops and aims to further the understanding of how workshops can facilitate interactive and creative knowledge practices in case study research. The paper builds on two research projects - where workshops were used to study the practices of professionals’ use of digital tools at a consultancy firm and the everyday life of residents in a newly built city district. In the project about professional practices, three workshops were carried out with professionals from different disciplines and focused on their use of a specific digital tool, BIM. Post-its were used to introduce, explore and discuss different topics around everyday practices and digital tools, both individually and in various group arrangements. The three workshops built on each other and resulted in a concrete action plan for developing the company’s work regarding BIM. In the research about the everyday life, the participants in five workshops were asked to draw a map of their home and other meaningful places in the city district. These individual “mental maps” were then used as a starting point for discussing the residents’ everyday practices in a group setting. While the workshops in the two research projects targeted different groups and had different forms, they both made use of visual materials as a central aspect of workshops. Therefore, we analysed the workshops with a relational material framework to further understand how design choices affect research practice and research outcomes. From this lens, we analyse our choices in designing the workshops, the analytical processes and the consequences these choices have on what knowledge we create in interaction with the participants.
