In this paper, the authors consider a novel eudaemonic approach to spatial design, proposed by Mikus et al., and examine how researchers and practitioners can co-design with participants to achieve a flourishing interpretation of Aristotle’s concept of eudaemonia (i.e., being one’s best self). The approach was tested in doctoral research conducted during 2021 at a time when many areas were under lockdown, necessitating a virtual approach. The research engaged nine older adults, aged 65–80 and living alone in Australia, and nine design professionals via creative methods including interviews, cultural probes, and co-design workshops. Combining these methods in concert with respectful engagement was found to produce not only the aimed-for principles to guide eudaemonic home design but also unintended yet beneficial consequences resulting from meaningful inclusive praxis. Here, the authors reflect on the importance of recognising eudaemonic design as a means of careful methodological praxis to precipitate promising participant outcomes, ranging from individual intrinsic motivation to collective mutual inspiration, to enhance the research experience, and to promote flourishing.
