Built two simple houses one after the other next two each other. Worked out fine. A third house (upper left on the screenshot) would then show red blocks even though Hearthlings should be able to reach there.
Tried it again without building next two a cliff (the three vertically aligned buildings on the right). They built fine until suddenly the error message below popped up. Before that and before building next to the cliff I built a trio of houses all at the same time and two of the half finished buildings showed the red blocks. No cliffs at that time.

If you’ll notice, your third in-progress house is actually intersecting your second. A fix should go out with our next unstable push.
