This graduation project explores how the architectural principles of Open Building can be implemented within an existing industrial structure to accommodate change over time. Starting from the notion that architects should not aim to predict the future but rather enable adaptability, the project questions the traditional role of the architect in residential architecture. By reusing the vacant Geschutfabriek -a former ammunition factory located at the Hembrug terrain in Zaandam- the project proposes a spatial framework that balances permanence and change. The building’s foundation and steel structure are repurposed as the permanent Support, while a newly developed infill system offers space for multiple dwelling typologies and public functions.

A flexible partitioning strategy, modular wall and floor systems, and a dry-assembled façade framework allow for varied and reversible configurations of interior spaces. The facade guidelines enable individual expression while maintaining visual coherence, turning the architect’s role for the façade into that of a framework designer. At the urban scale, a new public square, Geschutsplein, anchors the project as a central and multifunctional gathering space in the evolving neighbourhood. Passive climate strategies are embedded in the reused building envelope, supporting sustainable performance throughout the year.
