This paper explores the dimensions of how interest can be sustained in learners, using a case study of a makerspace in a Singapore context. We suggest a framework that synthesises both individual psychological aspects of interest development together with the impact of the socio-cultural environment which include five dimensions: community, culture, confidence, conflict resolution, recreating process. Based on a biblio-narrativical approach, we obtained data via interviews and field observations of students in the makerspace. The data obtained was able to substantiate our hypothesis of the impact the dimensions have on interest sustainability, emphasising the importance of a positive socio-cultural environment in interest development and sustainability. This has implications on the role stakeholders such as school management, teachers, peers and parents, have on an individual's interest development. The unification of psychological and socio-cultural aspects of interest development would provide a more comprehensive perspective on interest development and sustainability which would benefit both practitioners and researchers.
