Mate that's not really how exploring works, I (like most) spend literally days or weeks of my life researching & if necessary on the ground checking of places.
Access information is not something people just give others, unless they are known & trusted explorers.
I am mostly puzzled however why u didn't just message me?
To answer your question my visit was some time ago, there has since been a fire & a large portion of this is now gone. I also live over 100mile from this so have absolutely no idea what access is like now & finally u wouldn't of got in the way I did with "a lot" of equipment & a model IMO
