Medieval houses didn't have windows at the base levels where they were stone. Stone walls were to protect from thieves, raiders, and the elements. I don't plan on adding anything else to this kit. I am making a new medieval village kit as we speak, but it will still not have windows in the stone sections. However, since everything is textured, you will be able to simply paint stone into stucco to achieve this look. I don't have an ETA because... feature creep.
