How will we live together? With this graduation project a strategy has been developed to transform vacant heritage into cyclifiers, buildings that have a positive impact on their environment by creating a way of living together in balance with nature, humans, and buildings. Social public functions with a focus on healthy living, as well as a wide variety of housing types, create social interaction and the possibility for personal growth within the building. The concept of urban metabolism has been used in order to define and close cycles, on both the building scale as well as the surrounding neighborhood scale. In this way, a heritage project is created that has a positive impact on its environment.
