The builder in MineColonies is probably the most useful job, and the best one to assign your workers to in the beginning. The builder’s house block is made with a building tool, 7 wood planks and a door of the same type of wood. Once you place this on the ground, the villager with the best traits to be a builder will be assigned a builder’s role. Builders can still construct low level things when their house hasn’t been built, but in order to build high level things like a guard tower, or a miner’s hut, you need to construct their building. The Builder’s hut has different levels that let your Builder build higher leveled colony buildings per level of house.
