The bug
Like you see at the screenshot, there is a row of gras blocks inside the house.
The actual problem is probably that these structures don't include the air inside the buildings.

Confirmed, I commented about it at MC-73878.

Appears to be fixed in 1.10, when they changed village generation.

This time confirmed.
