Triodos Groenfonds co-financed the redevelopment of the industrial monument. The Hallen complex now houses a mix of commercial and social functions, among which a hotel, a library, daycare for children, and pubs and restaurants. Special fairs, expositions, film evenings and fashion shows are organised on a regular basis. Thus the building has become a vibrant centre in the city district of (Old) West that contributes significantly to reviving and reinforcing the local economy. Architect and project initiator André van Stigt: “Several hundred thousand people are coming to this area every year because of the Hallen. People even started calling it the ‘Hallen Quarter’.

Management of De Hallen is characterised by sustainable thinking, sustainable working, sustainable building and sustainable exploitation.
