FINALLY! I finished my first real Valix reference!
Note that the second and third pair of wings aren't drawn (as they are impassable). This only shows the main interior in the main and second Floor. Also, I left away things like tables and chairs since they can be shifted around.
Another thing not present on this blueprint is the water-supply. It's all stored in the basement underneath the main floor.
If you're familiar with the Valix and feel like something is missing, do tell me! XD
