At least 90 percent of my work is in situ. For me, it's not only to work with the architecture and space, it's also to work with the time, to work with the people who are involved with the place. It's also dealing with history. It takes all this into account. Other works can be placed in different environments, but they always follow a rule. This is usually not the case for work in situ, because even if they are transported, they remain there forever or they are destroyed.
