Finished up the final floorboards for the drawing room.
Then I took a good hour going through all my dollhouse supplies, rediscovering what I had, organizing everything on the shelves and searching for my floor plan, which I finally discovered on the last shelf. So I used the plan to cut out a ceiling for the room.
Placed a few pieces of bedroom furniture on top to see what that would look like.
Added the walls back in for the sitting room to the left, with a piece of matte board laid on top for a ceiling.
Which makes the side of the house look like this for now.
Then I painted the subfloor to the sitting room in black and took away one of the wall panels. Which makes it look like this.
I know I’ve debated having that extra wall section in or out before and I still haven’t made up my mind. The view is better without, but you miss that feel of the octagonal tower. I might leave it open down here, and add the last section on the next floor up for the music room and for the tower room on the top floor.
For now, be well.

Your finished floor is A Beauty, yet it is such a shame that that lovely center detail is obscured by the area rug, although I Know, You Know that it IS there. ;P
I have a dear friend who spent many hours inlaying a nautical compass point into the hardwood floor of her Victorian doll’s house, only for it to be entirely unseen after the floor for that particular room was installed. She like you is a perfectionist, particularly when it comes to wood. Such are some of the personal sacrifices which are often made in pursuit of authenticity as well as perfection, and I think that your parlor floor is indeed- Perfection!
