Abstract
This paper develops a practical framework for implementing circular business models (CBMs) in the design and planning phases of the construction industry. By synthesizing circular economy literature, industry case studies, and a survey of sector stakeholders, the study shows how modular construction, reclaimed materials, and service-based models can optimize resource efficiency and minimize waste throughout the built environment lifecycle. The framework features actionable tools such as material flow mapping and a circular economy model canvas to facilitate stakeholder collaboration and embed circularity at the earliest project stages. Results reveal substantial barriers to CBM adoption, including policy gaps, investment needs, and limited technical expertise, but highlight major potential for reducing environmental impacts, enhancing economic resilience, and aligning with global sustainability goals. The research concludes with recommendations for policy support, skill development, and future investigation into digital solutions, providing guidance for professionals aiming to drive sustainable transformation in construction.
