This thesis explores the integration of Circular Economy (CE) principles of narrow, slow, close, and regenerate in the social housing practice through digital technologies. Beginning with the examination of the CE implementation in Dutch social housing organisations, the research extends its focus to the broader built environment, introducing the Circular Digital Built Environment Framework and identifying ten enabling technologies. Subsequent chapters explore real-world applications of these...

This thesis investigates the introduction, adaption, and implementation of the modern concept of heritage conservation in modern China after the opening of its treaty ports. Through an analysis of the different layers of disseminating and receiving knowledge in transnational exchanges, it explicitly points out the divergence between the Eurocentric concept of conservation and the Chinese tradition of treating historic buildings and sites. As a result of the complexity of understanding and ada...

More and more citizens are entering the public domain and taking over tasks that traditionally belong to the government. For example, citizens increasingly run a community centre themselves, maintain the greenery in their neighbourhood and manage the local playground. To some extent, governments also encourage this behaviour and are disposing of social real estate. Against this background, this study examines the rise of citizens' initiatives in the Netherlands and how this takes shape in the...

Rapid urbanization has exerted unsustainable pressures on the environment, and implementing circular economy (CE) in cities has been seen by policy makers as a potential solution for resource scarcity. Scholars have therefore called for an understanding of the spatial aspects of CE that go beyond urban governance strategies, engendering the recent integration of spatial disciplines, such as urban planning and regional economics, into the study of CE.

Using the Netherlands as a case study, th...

Urbanized sandy shores around the world suffer from coastal erosion due to a lack of sediment input and sea level rise. These dynamics place new demands on coastal spatial planning. To compensate for coastal erosion in a more natural and systemic way, sand nourishments are deployed as a ‘Building with Nature’ technique, restoring the sediment balance and promoting dune formation as coastal defence.

In this research, Building with Nature is reframed as a landscape approach, regenerating t...
