A thriving city needs to offer affordable, healthy living and working space. By 2025, 1 billion houses are needed worldwide, of which 75% will be residential and 25% will be commercial. However, meeting this demand through current linear construction and housing practices will require an investment of around USD 9–11 trillion overall and have significant negative environmental impacts – such as the impacts from extraction that are felt locally as well as globally. Integrating circular economy principles into all the phases of a building’s cycle can work to meet urban needs for built space, while staying within planetary boundaries.
