About Builders Hut

Priority: High

The Builder's Hut determines how many construction queues you can run simultaneously. Every player starts with one queue — upgrading the Builder's Hut to unlock a second builder effectively doubles your upgrade speed.

Upgrade Tips

1Unlocking the second builder is one of the best early-game investments you can make.
2Use one queue for high-priority upgrades (Sanctuary, Barracks) and the second for resource buildings.
3Higher Builder's Hut levels also reduce overall construction time.
