Well if they were medieval then they are built according to standards.
Not wrong... Anyway I'm going to tell you something. If you get used to using these three plugins, you can create an airport terminal as you please! This is how i make them
A house that has a solar panel, and they provide the electricity generated by the panel to the government
Or
A house that has a solar panel + batteries, this means they won't need electricity to be powered as they power themselves.
I feel like both can end up the same , but just decided to make it into 2 different ideas because I think it's not possible to make electricity while being a residental building, and in the 2nd idea the solar panel is there only for decoration (and to cover the fact it doesn't require any electricity)
Also is it possible to create a residential building plugin that requires no electricity?(just asking because a plugin called primitive residential requires no electricity)
