Downtown is a place where people like to come, to meet other, to shop, to relax. Many inner-city areas are also historic, and simply pleasant places to spend time. But above the shops, it is often strikingly quiet and empty. It seems that across the Netherlands, there are thousands of empty floors above our retail spaces, which all in all could provide the space for 40,000 homes. ‘Time for change!’ says Hilko Hartog.
