How building works#

You have one builder: only one construction or upgrade runs at a time. A second builder can be hired for rubies for 3 days and 7 days.
Each level needs a minimum player level, shown in the tables below.
Levels that unlock up to player level 10 are faster and cheaper; the tables already show the discounted values.
The last 4 minutes of any construction can be finished for free.
Alliance members can help: each help cuts 3% of the level's build time (at least 1 minute), up to 10 helps per construction.
A building keeps producing at its old level while it is being upgraded.
Time skips (from quests, events and daily gifts) cut the remaining time of a construction.

Land size#

Every castle level adds land on all four sides, so you have room for more buildings and bigger statues.

Statues#

Statues are placed instantly, without the builder, and only raise Public order (some event statues also produce food or give a combat bonus). Each statue can be upgraded up to level 5; every level adds 25% of its base Public order, so level 5 doubles it. Statues from the build menu are upgraded with the same kind of cost they were built with; event statues are upgraded with rubies.
