A comparison of 1948 photos and post-Renovation photos indicates a difference in the distance between window sills and floor level in rooms on the western side of the residence floor. This suggests that the Renovation itself involved elevating the floor level west of the staircase landing, including the landing, perhaps to allow for a shallower pitch to the ramp from the landing to the level of the East Sitting Hall and adjacent suites. Such a change in the floor level, however, would have required a change in the floor of the balcony as well in order to keep it at the same level as the Yellow Oval Room. Attempts to contact likely sources of information on this matter have not been successful. Does anyone have information regarding this matter?
UPDATE: John sent a very informative pic of the door to the balcony.
