On the second floor, a line of cobblestone continues from the stairs into the floor. I would expect that the floor is completely from birch wood planks. This only happens on one side, but this is because the right wall is not included in the entrance structure.
note: you have to remove the carpets or the dark oak logs to view it.

Affects 23w33a.
To clarify, this occurs under the carpet of the doorway connecting the second-floor space above the entrance to the room to the left of it (when facing the entrance to the mansion from the front). It does not occur on the right side due to MC-203449.
