List of Building Materials Factories

Building Materials are also a very easy resource to produce. If you are producing enough surplus Power, you can produce Building Materials very easily. Kingwood Mills are the best Building Materials factories (as you can produce Building Materials 1:1), and Concrete Factories are the worst (as they take up a lot of Cleared Land and are really expensive to produce).
As of 2.2.1, there are 9 factories that produce Building Materials. 7 of these factories are renewable, while 2 are non-renewable. Quarries, Sawmills (Forest & Rainforest), Concrete Factories and Sandstone Quarries are available at t1. Oak Mills are available at t3, and Kingwood Mills, Stonemasons, and Stonesilver Quarries are available at t4.
