No, I mean the detail of the walls and where the bath and toilet were located as well as the area next door forming a passage towards the door that gives access to the corridor. Something that I find difficult to understand is the staircase that goes out of Alexandra's toilet to the mezzanine level. I cannot picture how that works...
Also the door(s) from the bedroom into the small chapel area, where in the alcove were they situated? I do not see the doors from the photograph itself that you have on the website.
Thirdly, you say the firm of Charles Berger in Paris exists to this day. I cannot seem to find it on the internet. Do you know more about it. I am sure they would have exact records of the colour and design of the mauve material that covered the walls in the Mauve Boudoir, and for that matter can re-create it.
