As others have already said - Admin is professionally sealed up. No getting in or out. And even if you did (using heavy duty tools to remove one of the steel panels that are bolted into the bricks, it will be very, very dark on the first 2 floors, and pitch back above those. They even replaced the old doors on the ground floor to make sure no one breaks in. Any tunnels leading into admin are also collapsed or sealed up.

There is still plenty of beauty to see in the wings though, which will be demolished are some point. The floors are highly unstable and nonexistent in most places, so, watch out.
