Reduction Building

Lowers Wood demand
Carpentry ( Seafaring )
Expansion requirements:
Wood and Marble
Use requirements:


Only the best lumbers are used at the Carpenter's Workshop. Therefore our handy craftsmen are able to build a solid framework and our houses don't have to be repaired all the time.

  • Every level of the Carpenter lowers demand for Wood by 1% per expansion (only in the town it is built).

Explanation of Reduction Buildings

All reduction buildings add their deduction percentage to that given by Pulley, Geometry and Spirit Level. This means the actual discount is an additional 1% per level of the reduction building, plus the reduction from the level of research you have completed. For example, a Level 1 reduction building combined with Pulley has a net of 3% reduction, with Geometry there is a net of 7%, and with Spirit Level there is a net of 15%. With the maximum level of reduction buildings (Level 32, 32% reduction) and Spirit Level (14%), the maximum reduction for that resource is 46%. This means you use only 54% of the original cost.
