De Wallen is the most famous and valuable urban area for showing the body and carnal desire under the circumstance of the society going on the way of spectacle. After years of regulation, overtourism and discipline, now the over-concerntrated prostitution windows have caused both social and environmental pressure in a small historical neighbourhood. This thesis aims to demonstrate how can urban design be used to propose an intense, theoretical and experimental city model for areas like De Wallen. The research proposed a multi-scalar strategy system from theories to analysis, and finally to design to help keep prostitution industry while reconciling the social conflicts between main stakeholder. However, the comprehensiveness of design across various scales and follow-up detailed consideration still need to be improved. Toward City of Enjoyment can be a continious topic to rethink about our life sphere, public space and city!

The province of South Holland has many important stakeholders and drivers that impact the economy of the whole of The Netherlands. This, together with the increasing global need for circularity, is why the province has an important task in the near future to take steps towards a circular economy. To address this task, this report has chosen to look into the agri-food sector, because of their high economical significance in South Holland, and the construction sector, because of the current and future high demand for housing. Both sectors also create large residual material flows. Minimizing the high amount of waste from both sectors is essential in order to reach a circular region. The existing approach in creating a circular economy is to often look at individual sectors and their material flows. This is logical, but adverse with the idea of circularity, where all chains are closed. We believe, however, that these problems don’t have to be solved within ‘their’ sector. Our vision to solve this problem is as follows: “In 2050, the material flow of the agri-food sector will be closed. All before-known waste is now used as a resource for the construction sector. Because of this, the waste of the construction sector is reduced. Because of the collaborative sector chains, they could now be seen as one interlinked sector. The South Holland agriculture sector is now a leading example for a symbiotic and self sufficient interlinked chain.” Our ambition is to create a new movement within the circular economy. Bottom-up initiatives show that it is possible to create interlinked sectors. This project will be a pilot in upscaling this idea, and proving this is possible and has greatly beneficial outcomes. The pilot focuses on using agri-food residual flows as a resource for the construction industry of South Holland, but can be an inspiration to interlinking other sectors. To approach the interlinking of sectors, we envision a few strategies. We will be bringing the pieces of different policies together, use education and knowledge as glue between the sectors, and use transport and infrastructure to support the connection. Spatially, this results in four types of transition areas, a new living environment where the two sectors come together, also impacting the surrounding areas. This also impacts citizens from a socio-economic perspective, because more cross-sector jobs will be created and competition between businesses will be stimulated, which drives them to become more circular.
