This view, from the office door, shows the elevator across the way, the open front door and a glimpse of railing, a suggestion (Ha!) of the coat rack and shelf, and to the left, the door to the basement is open, but you can't see the stairs from this angle. (Nor the stairs going to the upper floors.) I don't think Wolfe used a glass door on his elevator, but of the choices I had, this seemed to best give the idea. For a view from the front door down the hall, see The Front Hall.
We can't see the pantry to the right of the dining room (just visible), and I don't really like the table where Archie eats breakfast, but the rest of the layout gives Fritz what I think he would need. Beyond the center table you can just make out a backed stool where Fritz reads his paper.
