Went here yesterday and as much as I hate to disagree it actually does still have a fair bit inside and I'd say not a bad explore. Lots of personal effects and some of the rooms still fully in tact- especially the kitchens.
However it is pretty well secure and there is indeed a guard with a German Shepherd patrolling so not for the faint hearted. Work has started and new fences are going up, a site office has been erected and skips have arrived. Not long left if anyone wants a nosy.
