Technology tree
The Technology Tree progresses access to Buildings for a settlement. Each building gets unlocked by constructing and using previously unlocked buildings.
Each settlement begins with the Hut, Potato Patch, Water Pump, and Woodcutter unlocked.
Unlocking buildings
Other than the four beginning Buildings, every building on the Technology Tree has a prerequisite, conditions that must be met before the building can be unlocked. Typically, this is another building's construction and initial successful use.
For example, to unlock the Compost Heap, the Landscaper must be unlocked and constructed. Clicking on the Compost Heap in the tree highlights the line coming from the Landscaper—this highlighting can be helpful when finding a distant prerequisite. It also highlights the line going to the Tree Nursery. The nursery requires both constructing the Compost Heap and producing 10 Compost in it.
Categories
The Technology Tree shows Buildings in eleven columns, shown in stripes and with a colored label at the top and color-matching icons.
For example, all Accommodation Buildings appear in the leftmost column, on the lighter stripe, under the dark teal Accommodation label and each with a dark teal hexagon-bordered icon. A building's prerequisite is often in a different column.
