The current building environment has a lack of adaptability, which means that buildings are often demolished and rebuilt. In almost all cases, biological and technical materials are mixed by using glues, adhesives or wet seals, therefore materials can hardly be reused, if at all.

After demolishing, there are not always instantly new permanent plans in the Netherlands due to an unfavourable location for example, which can lead to unused areas. These areas can stay untouched for years even for some decades, while there is a shortage of housing for starters and students for example.
