Climb the fence, find a way to document what is happenng. It'll make for nteresting shots, and maybe provide the "kick iin the pants" needed to get the restoration project up and running.
I did this with a "konigshof" here in Germany. (A place where a Kaiser would stay overnight where traveling through the region.) Built in about 1400, the place was falling to the gound, roof sagging, really sad. Comments were, the place had to be restored according to historical guidlines, which was cost prohibitive. FINALLY, a group of banks and other companies bankrolled the project. The architect and others responsible were thrilled to learn that I had documented the place in near ruines. They also commisioned me to do the "after" shots as well. Turned out fine in the long run. The place is being saved, as well as my bank account
