More and more people in the Netherlands want to live in the so-called Randstad. This results in a need for densification in Dutch cities. One of the solutions for this is building more high-rise residential buildings. High-rise buildings provide amazing views and house many people on a small plot of land. They do however, have some downsides. According to their residents, the circulation space can be impersonal and the use of the elevator can be experienced as annoying. Even though this is the place to see and meet your neighbours. It has also been proven that there is a relationship between living in a high-rise and poor mental health of children. And lastly, high-rise dwellings are often seen as a home to eventually move on from, to an owner-occupied home, which results in a lack of connection between the residents and the building. This graduation project aims to rethink the current way of living in high-rise buildings to make it more suitable for families with young children by answering the following research question: How can a high-rise residential building contribute to improving the living environment of children in cities while stimulating a sense of belonging to a high-rise community in Rotterdam? As a result of the research a set of design tools and guidelines is developed to form the base for the design process. The final result is a high-rise residential building in the centre of Rotterdam that is suitable for children of different ages and encourages social interaction to increase the sense of belonging to a high-rise community.
