The adaptive reuse of military heritage sites often presents a paradox between the integrity of its heritage values and the implementation of contemporary reuse programs. This project aims to adaptively reuse the former Officierscasino in Soesterberg, a Dutch national monument with an introverted character rooted in its military history, as a contemporary, public-oriented, extroverted art complex. Employing a research-by-design methodology, the project utilized a phenomenological tool to investigate the introverted character and translate it into executable design guidelines, which in combination with a value assessment, formulated a design position opposing the extroverted reuse program. The tension between introversion and extroversion was then resolved via multiple design interventions, eventually creating an architectural scheme that balances introversion with extroversion, privacy with publicness, and old with new. The project ultimately provides a methodological framework to incorporate intangible spatial phenomena into heritage conservation, demonstrating how exclusive monuments can be appropriately transformed into inclusive public spaces through architectural interventions. ...
