Your question demands a more complete answer, Asher. Here it is.
Please keep in mind that this is Germany, and there are no squatter laws. When the army left the place and sold the land to the city, it was planned from the onset to demolish the houses. The artists were given a temporary permit to rent atelier space for a few years only. So the destruction was planned.
The creation wasn't.
There was more on the grounds that I was able to see, most notably a night-club for sado-masochists and a large music hall. And more ateliers. So the land was put to some good use in the intermediate time when the city planned what to do with it.
A few houses were listed and kept as a testimony of the architecture of the barracks. These are still used to lodge policemen today. The rest is being demolished as we speak.
What about the artists? A limited number were allowed to stay in two houses which are on the side of the main grounds. I will present them in the second series. The rest of them had to go.
Why? Because of money. The land is worth millions and art has no clear value. The same story is happening all over Germany. You may want to search for "Tacheles" in Berlin: same story and closing this month. I gave a warning at the onset: this is a sad story with no happy end.
After wandering through the abandoned houses with my camera, I finally came to a big room where the artists had left a message. What significance this place had for them. Here it is:

This is the end of the first series. It gets worse in the second series.
