I wish there was a floorplan of the place that we could get access to, and there actually might be one, IF we could figure out where it is and how to get a copy of it.
Until and unless that happens, I've combined written descriptions, observations of the limited photos we have, and some educated guesswork to put together a rough idea of the house's layout.
Basement: Servants' quarters, boiler, laundry room, misc. storage, wine cellar (see last paragraph below).
Main/First Floor: Living room, den, dining room, kitchen, one bathroom. A small barred window can be seen to the left of the front door. This probably serves a small reception room/cloakroom where visitors were "parked" until the lady or master of the house was ready to receive them. There may also be a small "telephone room" somewhere nearby.
Second Floor: Four family bedrooms, two bathrooms.
Third Floor: Ballroom. Putting a "ballroom" in what otherwise would have been an attic was a fairly widespread practice.
Looking at the left end of the house in the picture published with the newspaper article shows windows that clearly establish three floors above-ground. This reopens the question of just exactly what the sloping "something" visible in the large window is.
As for the layout of rooms on the different floors, my guess is on the main floor of the large wing: living room, dining room, kitchen. In the small wing: den and maybe a bathroom.
On the second floor: three bedrooms and one bathroom in the large wing, master bedroom and one bathroom in the small wing.
I've already mentioned the ballroom on the third floor. As I've said, this is mostly guesswork, and I would welcome any other input or discussion.
On a different but somewhat related note I once had the opportunity to tour a privately-owned house here in Portland that is of the same age and style as this house. The wine cellar in the basement had what looked like kitchen cupboard doors on all the racks, and there were narrow shelves in front of the racks. I haven't been in many wine cellars, but this all seemed a little strange to me. However, it finally dawned on me: PROHIBITION. Put jars of preserves on the narrow shelves, close the cupboard doors, and the wine cellar becomes a "fruit room." I wonder how many other houses had similar setups?
