I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Basically a big old empty metal-clad warehouse with a two-storey section inside. All of the doors and windows are missing, as are the skylights. There's plenty of parking right next to the place. I have flown here loads over the last few years and never seen a soul in the place, nor got any grief from anyone. (I usually fly here Sat / Sun - would be busier during the week due to location)
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 02/06/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
