This study looks into the variables of stakeholder engagement and the implementation of R-strategies in new housing developments with the goal of identifying motives, difficulties, and opportunities. The study promotes sustainable urbanisation by providing stakeholders with ways to improve circular innovation in housing development and fill knowledge gaps regarding stakeholder engagement in the research field of circular economy. This study employs qualitative analytical techniques, including thematic analysis and software coding, to extract structured insights from interviews with stakeholders in new social housing developments. The methodology centred on identifying common themes and trends in the data and ensuring thorough coverage of all stakeholder views. This study investigates stakeholder interaction during the conceptualization stage of a project, with an emphasis on the application of R-ladder principles. It highlights constructors as critical in enabling collaboration among varied stakeholders, including project developers, environmental consultants, architects, contractors, and municipalities, in order to achieve sustainability goals and manage regulatory difficulties. Social Network Analysis (SNA) gives useful insights into stakeholder interactions, despite limits in capturing human relationships and subjectivity in data collection. Efforts to mitigate biases, such as using the snowball sampling method, address issues like potential sampling bias and limited generalizability. Moving forward, this study proposes stronger stakeholder engagement frameworks and governance structures to increase the adoption of circular economy principles in the built environment while addressing issues like financial limits and regulatory ambiguity.
