Hello Helly Angel,
Hope you don't mind my re-activating your old thread but its the only dedicated one to the Braunes Haus found readily when did a search. You might especially find interesting what wanted to add here. I was going through old photocopy boxes and thought the board might like to read the Adolf Dresler description of the Brown House. His 1939 book "Braunes Haus" was captured and put in the Library of Congress. Back in the 90's made photocopies. The book actually deals also with other buildings like the Fuhrerbau and incidentally mentions by that time which functions had moved out of the Brown House. But the 10 pages relevant made into a pdf for all. If any want to post the individual pages let me know.
The National Archives also has a large photo collection series. Using some of the descriptions in the book and sources, have puzzled out some of the arrangements. Not to Reichskanzlei or Berghof clarity, but enough many may find it interesting. Turns out the pictures appear to have been taken in December 1931, and early 1932. The clue is the wing office building behind the Brown House is in them and that was newly finished only after end of 1931.

Have fashioned some montages to make clear where each room was as discovered so far. Will spread over a few posts. The first set here are as we come to the entrance under the balcony, walk through (look back behind at reverse side of door), and then enter the lobby "Fahnenhalle" where the porter's desk is, the bust of Bismarck on a pedestal on Helly Angel's color picture above, the `Bludfahne' (Blood flag that gives its name to the hall) and the staircase on the right east side leading up to the First Floor.
Enjoy,
