The global housing affordability crisis sees European countries searching for solutions, paving the way for transnational knowledge exchange. The efforts to fulfill this potential within the housing sector and transnationally are, however, unexplored in relation to the affordable housing crisis. The goal of this thesis is to deliver lessons-learned for transdisciplinary and transnational knowledge exchange with specifically affordable housing provision in Europe. A case study will be performed on 'cost rental housing', a current measure to improve housing affordability which benefited from transnational knowledge exchange, in Ireland. Stakeholders are interviewed about practical insights, the barriers and enablers of knowledge exchange, their incentives and the methods used to facilitate it. With insights from
both practice and literature, lessons-learned are established from both the introduction of cost rental housing itself and the transdisciplinary and transnational knowledge exchange efforts.
Combined, the research ultimately delivers seven key lessons for transdisciplinary and transnational knowledge exchange with providing affordable housing in Europe.
