With the worldwide biodiversity decline and cities that should adapt to climate change, rewilding the built environment to restore biodiversity and increase the degree of natural areas is necessary. Yet, there is currently no established overview of potential rewilding strategies for urban environments. This study explores various opportunities for rewilding the built environment through nature-inclusive design and presents a toolbox that architects and urban planners can implement in the design process to create opportunities for biodiversity and make cities greener and more resilient. Furthermore, the suggested framework can be used to create strategies on the larger scale. Rewilding strategies, however, are highly dependent on the characteristics of a specific environment and thorough site research is necessary to come up with suitable strategies. The typical Dutch post-war neighbourhood Boerhaavewijk in Haarlem is taken as a case study to demonstrate the application of these strategies.

With a shortage of over 300,000 homes, which will be even more in the coming years, the Netherlands has a social problem that needs to be solved (NOS, 2021; Bremmer & ten Teije, 2020). The Netherlands also needs to take more progressive measures in the field of sustainability in order to meet its goals. The relatively young concept of "tiny house" offers solutions for this (Obbink, 2020; Shearer & Burton, 2019; The International Institute for Industrial Environmental Economics, 2013). However, because it does not yet have global recognition and the tiny house movement is still very young, there is a need to first understand what a tiny house entails, where this movement comes from, and what the reasons are for people to switch to this lifestyle. With the answers to these questions, a more concrete look at the Netherlands will be undertaken. Literature research will be conducted and existing research based on surveys with tiny house enthusiasts will be used to provide answers to the above. This thesis contributes to the interdisciplinary literature on this topic. With the outcome that tiny houses can offer solutions to the housing shortage in the Netherlands and in the field of environmental sustainability, it is recommended to conduct deeper research in the future to get an even better grasp on what ways tiny houses can contribute to this.
