Never noticed any cars etc inside the padlocked/barbwire gate at the front, seen the odd car around the side of the building (to the right of the main gate)
The carpark is used by the building directly at the side. The gate is open for that reason. Also if they see anyone in that gate they will and have called the police has they pay to park there. I'm guessing it's private property and you could be robbing cars etc. But it's not worth it cause from in there it's proper blocked up. The caretaker who lives just behind is very good at sealing it up. The only reason I know is I spoke to the people who own the carpark to get info on owner in the early days to try and set a permission visit. And since the roof incident in which 3 guys where jailed for theft after they cut the lock and drove in to steal lead from roof and was caught. The gate is well watched and not worth the risk.
