In order to realise this project, quite a few legal loopholes and exemptions had to be either found or created. There was one legal exepmtion that was crucial to the success of the project, and that is the option for Dutch citizens to form a “collectief particulier ondernemerschap”, or CPO. A CPO is a form of social organisation that allows the residents to collectively act as the client for their housing development project. United in the CPO, the future inhabitants gained full ownership of the land, as well as full responsibility over the design and construction of the buildings. By teaming up with a construction manager, architect and contractor of their choice, the future residents not only cut costs by an estimated 10-20%, they also gain a large degree of control over important design decisions in order to meet their demands and desires.
