Industrial Lumber Mill

The Industrial Lumber Mill is the Iron Teeth faction's enhanced wood processing building, unlocked for 500 Science Points and designed to outperform the standard Lumber Mill in both speed and worker efficiency. Built from 20 Logs on a 2x3 footprint, this structure employs 1 to 2 workers and requires 75 horsepower to operate. Its innovative design fits more workers into the same production space, processing 1 Log into 1 Plank in just 0.63 hours, roughly half the time of the standard Lumber Mill's 1.3-hour cycle. Internal storage holds 13 Logs and 13 Planks, identical to its standard counterpart.

The performance advantage of the Industrial Lumber Mill is substantial. With 2 workers assigned, it outperforms two standard Lumber Mills while consuming only 75 horsepower (compared to 100 for two standard mills) and costing just 20 Logs to build (versus 30 for two standard mills). This makes it strictly superior in terms of power efficiency, construction cost, and footprint. The 75 horsepower requirement is constant regardless of how many workers are assigned, so running it with 2 workers maximizes your return on power investment. Planks produced here feed into the same downstream chains as always: the Gear Workshop for Gears, the Wood Workshop for Treated Planks, and various construction projects.

One important consideration is that the Industrial Lumber Mill consumes power even when no workers are assigned, so pause or demolish unused mills to avoid wasting energy. Position it near your Lumberjack Flags and Log storage for efficient input, and close to Gear Workshops and Wood Workshops to minimize Plank hauling distances. As the Iron Teeth faction specializes in industrial efficiency, the Industrial Lumber Mill embodies that philosophy perfectly. Build your first one as soon as you unlock it, and transition away from standard Lumber Mills to consolidate your wood processing into fewer, more productive facilities that leave more room and power for other industrial operations.
