Buildings are the backbone of your dominion and provide you with production and various bonuses.

All constructed buildings except for Homes and Barracks provide 20 jobs and which are automatically filled by unemployed peasants. During construction all buildings provide 15 population. All constructed buildings except for Homes and Barracks provide 15 raw population. See population for explanation on the difference between raw and modified population.

Buildings can only be constructed on acres of barren land. Buildings cost platinum and lumber, and require 1 acre of barren land. The cost in platinum and lumber increases depending on your total land size.

Each building can only be built on a specific land type. The land type for each building is always the same, except for Homes, which depends on your race.

All buildings take 12 hours to build. You can instantly destroy buildings.

Constructing buildings costs platinum and lumber. The formulas are below.

Acres gained by Invading someone 75% or larger will be discounted. The discount starts at 50%. After Day 25, the discount grows by 2% each day until a maximum of 70% reduction is reached on Day 35. In addition, if you are invaded, lost buildings will give you the same discount. As of Round 18, these discounts do not stack.

Platinum cost[edit]

(ExploredAcres - 250)*1.25 + 850 + ConqueredAcres

Lumber cost[edit]

(ExploreAcres-250)*0.285 + 87.5 + ConqueredAcres/4.25

Bonuses from factories, techs, wonders, etc, are added together, to a maximum of -75%, before multiplying these cost formulas.

Destroy Building[edit]

You can destroy buildings by going to the Destroy Buildings page.
