Yes it was an article 31 prohibition notice.
The means of escape from these two first floor rooms was pants- an internal stair which was open at the bottom to the main bar, enclosed at the head, with an alternative french window exit from one room leading onto a flat roof and then to a vertical ladder, with a bypass door to enable the occupants in the second room access to the roof exit. So it was pretty poor - even by 1971 standards. If there had been an external rather than a ladder then it would have been more or less ok.
Appeal- no. Within a week of the prohibition there has been an internal protected route installed leading direct to a final exit. The RRO has worked and has led to improved standards. The destination is great, the route to get there a bit dodgy. Just makes you wonder why it did not happen years ago. Would a letter of recommendation have done the trick? To be honest I doubt it, but it would have smoothed the road.
