Your use of odd numbers on 2 house designs as well as in 2 other locations between a building and some other feature (such as the mountain side, distance of 3) shows that you need practice scaling before I can allow you to try something like Johto. If Johto had only buildings to do, it wouldn't be such a big idea. But most buildings are done, and the region needs to expand, which requires the most annoying attention to scale imaginable.
