This graduation project focuses on how architecture and the built environment can provide a child-friendly and future-proof childhood in the inner city. In the Netherlands we have got the phrase huisje, boompje, beestje. This symbolizes the phase of young couples who are going to settle and are having a nice, quiet and standard family life. For many of those the social succes image includes a single-family home with a garden. Apartment living is widely seen as inappropriate for children and therefore they think that this is the best place to have their huisje, boompje, beestje. This project will show that this can be done differently and can change into a new culture: appartementje, boompje, beestje.
