Buildings & construction
Every construction order has a target level, cost, prerequisites, and base duration.
Level gates #
Updated for game update #110 (merged 5 October 2026): From Hall level 6, the four producers need level N−2 instead of N−1, and Walls are only required at Hall levels 10, 15, 20 and 25.
The Town Center Hall starts at level 1. Up to level 5, upgrading it to level N requires Farm, Lumber Camp, Quarry, Iron Mine, and Walls at N−1. From level 6, the four producers need N−2, and Walls need N−1 only at Hall levels 10, 15, 20, and 25. Other buildings require the Hall at their target level; Castle also requires Hall level 15 for its first construction. Maximum building level is 25.
Costs and timing #
The first Farm, Quarry, Lumber Camp, and Warehouse are free. Other prices scale by building and target level; Metal begins at target level 10. Walls have their own Wood/Stone price order. The level tables show the current exact cost and base duration before VIP.
Queues and cancellations #
A city can have two construction orders running. A canceled construction order returns 50% of its paid resources. Completion and production continue during offline time.
