This project explores the potential of the church vacancy to tackle pressing issues of daily work commute to Luxembourg City. Particularly, in the period of land commodification it is crucial to consider urban vacancy as a collective resource to rethink the modes of living, working, and utilising the space commonly. Through the adaptive reuse of the St. Barbara church in Differdange into a worker cooperative, it strives to shed light on the future of work and working spaces organised around principles of self-governance where workers are the ones who take care and maintain their work environment. Within a secular society’s framework, these 21 churches are redefined as commonly used spaces for a shared economy, knowledge, values, and responsibilities.
