Building

Construction office

The heart of every castle: you order all construction here, and every level cuts the build time of all other buildings.

In your Construction office you order every upgrade and every demolition in your castle. The column “Build time of other buildings” shows how much of the normal build time is left at that level. The first levels bring big jumps; from level 72 the minimum of 1% is reached – a build then takes just one hundredth of its base time.

The same speed-up applies to demolitions and to repairing damaged construction sites. Only the event buildings elf workshop and hen house always take the same time. Important: the build time is fixed when you place the order. A running build does not get faster if you upgrade your Construction office in the meantime.

Your Construction office unlocks many buildings – the “Required for” list shows at which level. From level 25 you can also demolish buildings in this castle; Demolishing buildings explains how.

Build even faster with the Athanor skill “Masons’ Guild” (Quintessence) and on worlds with a higher build speed (Worlds). How many orders run at once and how instant build works is explained under Build queue & instant build; the Building master keeps building while you are offline (Masters).
