We need to build more homes and we need to do it now. Short-term thinking that is inherent in the current process of urban development has huge social and environmental impacts. In the short and long term. Our project, the long-term business model of a Community Land Trust, demystifies the financial part of an urban development and assures community engagement and affordability. To show the challenges and long-term benefits of this model, we compared it here with the popular Dutch mid rent model which similarly aims for affordability, but only succeeds in the short term.
