Apparently, that one doorway was the only access into the projection room. Odd indeed, that there was apparently no access from inside the house ... That lower doorway at the front apparently led into the basement, not the projection room. This doorway led into a "Schaltraum" (switch room ?) then into the basement area via steps. I've never read this anywhere, but I assume that basement workers used this Schaltraum to access the basement without having to go into the house itself (there was apparently also basement access from the old Haus Wachenfeld part and also from the main entry corridor behind the Great Room ... I think).
This part/angle of the Berghof was not commonly photographed, but here are some views. In some of these you can see another small window low down near the front corner of the house - this was entry for outside air into the basement ventilation room (also bars over this window).
