Contemporary adaptations of 19th-century Antwerp townhouses into multiple-family dwellings
 

This thesis determines how to preserve and adapt built heritage while adding density to the urban fabric of historic cities. Densifying existing houses could be an effective alternative for urban sprawl, which is unsustainable and puts cultural heritage at risk by causing heritage assets to become fragmented and deteriorated. The main goal is to investigate the current strategies used to densify townhouses from the 19th century in Zuidwijk, Antwerp.

By creating a database on the historic and current situation of these 19th-century townhouses in Zuidwijk, tendencies regarding their residential use and densification are analysed. Additionally, a qualitative categorization of various adaption strategies for the same townhouses is created by examining building permits that are accessible through archived and on-site research.

This study shows that Zuidwijk is experiencing a trend of single-family townhouses being adapted into multiple-family residences. This adaptation can occur through a variety of strategies. Selecting the appropriate typology for a given building is crucial within the adaptation process, as it determines the potential of the existing townhouse and the objectives to be achieved through the adaptation. This thesis aims to serve as a basis for conducting more in-depth research into the phenomenon of adapting historic residences into multiple-family units, exploring its range of opportunities.

Identified research limitations include a small case study sample, mainly analysed without on-site visits and assessed from an architectural and heritage perspective. Further research and more detailed data regarding criteria such as policy and sustainability, should be considered in the future.
