| This section is in need of revision.
Please help improve it or discuss these issues on the talk page.
The reason given is: WIP page. Need categorization. Need more information about what a building blueprint is. Maybe Maybe merge with Building Design if it isn't too complex or focused on designing.
Building blueprints can be published for free on the building blueprint exchange so it is usable from the Construction window directly, or it can be published for a price that requires players to buy the building blueprint before they can use it.
