What makes special production buildings different is that most of them allow also to produce other resources beside supplies. Special production buildings can also be upgraded to higher ages with the Renovation Kit or the One Up Kit to increase their output. Like regular production buildings special production buildings require some amount of population to be available to be built. For all the buildings the required population will increase when the building is upgraded to a higher age, except for the Mad Scientist's Lab and the Witch Doctor.
Most of the special production buildings also allow to produce other resources besides the supplies but there are some that only produce supplies. Since those buildings can be upgraded the table below gives exact production amounts only for the resources that are constant through the ages. The goods that are produced are from the buildings era not from the era the player is currently in.
|Arena of Victors||4x5||5||2|
|Blooming Cider Mill||3x3||1|
|Fruitful Cider Mill||3x4||2|
|Bountiful Cider Mill||3x5||5||3|
|Prosperous Cider Mill||3x6||10||4|
|Gondola Dock Market||4x5||1||10|
|Mad Scientist's Lab||4x4||1||15|
Below are the tables that presents the goods and forge points production efficiencies of special production buildings. It shows the maximum potential production in 24 hours per one tile that the building occupies. The calculations consider the buildings with 8 hour production option to do three production cycles in 24 hour time. Note that this is the maximum potential and real life results may vary.
Those are simple efficiency calculations that do not take into account the population requirement of the building nor the road connection requirement. For example each of those buildings require population. The required populations increases every age except for the Mad Scientist's Lab which requires 2 population in every age. This makes it more efficient in later ages however those tables do not represent that.
