Just to add some info relating to the above scenario - would appreciate any views:

The means of escape from the bedrooms is via an enclosed stairway that discharges to the restaurant dining/bar area on the ground floor. A self closing 30 minute fire door has been fitted to the bottom of the stairs at ground floor level and the doors to the bedroom are self closing FD30S.

The kitchen is at the rear of the restaurant area on the ground floor and people (accessed via fire doors and fire resisting construction).

The local fire officer has instructed that an additional escape stairs should be constructed, but I can not find where the current scenario is prohibited under current guidance. Would you consider that the restaurant area on the ground floor forms part of a protected escape route? Given that it is compartmented from the stairs and the kitchen?
