This Interreg NSR ProCirc pilot project is situated in the harbour area of the city of Leuven and spans across two iconic buildings. In 2016 the local authority acquired ‘The Mills’ site, a former wheat mill complex with adjacent offices, laboratory and residential building. The use of this site is guaranteed for at least 10 years. ‘The Silos’ were bought by a project development company which offered use of the site’s ground floor for temporary occupation until the end of 2022, when it needs to be returned in its original condition. This created an opportunity to answer the need for a circular hub in the city, with space for creative and educational activities. As circular construction is one of 5 priorities in Leuven’s 2050 net zero roadmap, the final piece was added to the puzzle.
