Forests are gifts from Mother Nature, and the lumber mill is where we make our own treasures out of wood. However, due to excessive deforestation, this precious property of mankind is quickly disappearing. Maybe it's time to stop now, what do you say?

Building Lumber Mill 1 5.png
Unlocked at: City Hall Lv.2 — Additional building unlocks at: Lv.5, Lv.8, Lv.11

The Lumber Mill produces wood for collection by the governor. It is one of four such resource production buildings, along with the Farm (food), Quarry (stone), and Goldmine (gold). Each upgrade of the lumber mill improves its wood production per hour and its max wood capacity.
