My graduation project focuses on making middle-rent homes in existing social rental homes in Amsterdam Nieuw-West, in which the amount of social rental housing is maintained. In Amsterdam there is a growing shortage of middle-rent homes for starters. As a result, people stay longer in a social rented homes while these homes often no longer meet the changing needs. A large proportion of the residents live too large or too small. The aim of this design project is to promote the flow of social rent to middle rent so that starters do not leave the city. In Nieuw-West about 60% of the social rental is walk-up apartments. That is why I decided to make a design for these apartments in Nieuw-West. The walk-up apartments on the Maassluisstraat were chosen for the design project, because of the high number of houses and part of these blocks have already replaced with new buildings.
