I used to wander around in Utrecht where I live. I found this house in a fenced-off area behind a church where there was just concrete on the ground, it had been like that for a while. I cycled past a few times but this was the first time something was there, I remember going back a few times and it had gotten bigger. I think it's the work of kids, who built it with the stuff they found on the site.
