Overview
The UCL Institute for Innovation and Public Purpose (IIPP) is pioneering a mission-oriented, rights-based approach to housing policy, viewing secure, affordable, and sustainable housing as essential to public value creation. IIPP challenges the treatment of housing as a financial asset, advocating instead for models that prioritize social outcomes, long-term affordability, and environmental sustainability. Through empirical research and policy engagement, IIPP explores how public purpose can be re-centered in housing systems. By positioning housing within broader strategies for equity and climate justice, IIPP aims to reshape the housing landscape toward the common good.
