This research explores the relationship between industrial heritage and human well-being in the Waterdriehoek region of the Netherlands. It is focusing on the steel factory buildings in Alblasserdam. As many industrial structures from the late 19th and early 20th centuries face vacancy, the challenge of revitalizing these sites while addressing environmental and health concerns is crucial. Using a qualitative approach, the study combines desk research with a case study of the steel factory to assess its architectural qualities and impact on human well-being. Key questions investigate the preservation of industrial architectural values, the coexistence of heritage and residentials, and design strategies that promote well-being. Findings indicate that while the factory's features, such as natural light and spaciousness, enhance user well-being, challenges like pollution and limited green spaces remain. The research emphasises the importance of a comprehensive design approach, argues for strategies that integrate social, natural, and evidence-based elements. This approach aims to connect historical industrial use with future community needs, ultimately fostering well-being in revitalized areas.
