Buildings are structures that can be built by Beavers and Bots.
Most types of buildings have to be unlocked once spending Science Points.

Construction

Paths can be built directly and for free, flags are free but need building time, all other buildings need time and materials to be constructed.

Builders

In general, when a buildings is placed on the map, it first appears as a construction site. It won't work in any way before it is constructed by builders: Beavers and Bots employed at a District Center or Builders' Hut.
Builders carry the needed materials to the sites and spend some time there doing the construction work. If all the needed materials aren't available, builders will transport all available materials to the construction site and carry out part of the construction work accordingly.

Each construction site can be turned off, preventing beavers from placing materials or proceeding with the construction of that building.
Constructions sites can also be assigned five priority levels, ranging from "Very Low" to "Very High". By default, each newly placed construction site will have "Normal" priority.

Construction Order

The execution order of building jobs is determined by three factors:
First, whether a site is turned on, reachable by builders, and the buildings below are finished. (If the last one is true, the site will be visible on the map as sticks on the floor.)
Second, if it is reachable, the priority which was assigned to the site.
Third, if they have the same priority, the order in which the sites where placed.
An exception is Terrain Blocks, where arrow direction is followed before placement order.

However, if many builders are working at the same time, they can possibly overtake each other and the order gets mixed up.

The execution order is of course important whenever things are time-critical. It should also be considered in those cases where the access to construction sites can easily get blocked if the order hasn't been set properly. Otherwise, additional scaffolding may be needed.
Also, builders (and others) can get stuck if their way back is blocked by just-completed buildings.

Classification

Menu Groups

There are (14) groups of buildings. Each group provides different kinds of capabilities or deals with different kind of Needs.

Decoration

Main article: Decoration

Decoration buildings mostly satisfy the beavers' different aestethics need. Decorations also allows access to fences.

District Management

Main article: District Management

District Management buildings add builder capacity and the abilities to haul goods within a district, establish new Districts, and distribute goods from district to district.

Food

Main article: Food (Building Group)

Food buildings provide beavers with the abilities to gather, plant, harvest, and process, food and ingredients to satisfy beavers' hunger and nutrition needs.

Housing

Main article: Housing

Housing buildings satisfy the shelter and sleep needs. Each faction has unique housing options.
This building group also deals with controlling the population growth. Folktails do so by controlling the number of beds, Iron Teeth by operating Breeding Pods.

Landscaping

Main article: Landscaping

Landscaping buildings add the ability to block water, either adjustable, completely, or partially. They are mainly used to accumulate and hold Fluids before and during a drought.
The explosives factory and the dirt excavator also create abilities to change the landscape by either removing or adding terrain.

Metal

Main article: Metal

Metal buildings add the ability to collect scrap metal from ruins and process it into metal blocks.
Metal blocks are construction materials needed in mid and end game.

Monuments

Main article: Monuments

Monument buildings satisfy the Awe needs category. All monuments are faction exclusive.

Paths and Structures

Main article: Paths and Structures

Paths and Structures buildings add the ability to freely build paths to connect buildings together. This category also contains stairs, platforms, and bridges.

Power

Main article: Power

Power buildings add the ability to generate power through either, beaver power, engines, water wheels, or windmills.
Power is measured in hp and can be distributed via power shafts and consumed by powered buildings.

Science

Main article: Science

The basic science building is the inventor.
The inventor is important early on. Without them, beavers are unable to produce science and without science, beavers will be unable to unlock new buildings. It is highly recommended to build at least (1) inventor in early game.
The science category also includes the different buildings to construct Bots and satisfy their needs.

Storage

Main article: Storage

Storage buildings enable beavers to store logs and certain materials in piles, most kinds of goods in warehouses, and water and several liquids in tanks.

Water

Main article: Water (Building Group)

Water buildings add the ability to dump and pump water to satisfy beavers' thirst and to allow crops and trees to grow.
There is also a stream gauge measuring water flow and depth to keep an eye on water reserves. This category also includes buildings to pump badwater, seal badwater sources, and process badwater into useful Extract.

Well-Being

Main article: Well-being (Building Group)

Well-being buildings are mainly used to satisfy the beavers' secondary needs like fun, social life, spirituality or health in order to increase their well-being.

Wood

Main article: Wood

Wood buildings provide the abilities to cut, plant, and tap trees to obtein, among other things, the most essential good in the game: Logs.
It also contains several workshops to process wood into Planks and a variety of other products.

Construction Features

Buildings can have special characteristics determining how they can be built like ground-only or above-ground.

Solid

If another building can be constructed on top of a building, it is marked as solid.
Complete list of solid buildings:

Bot part factory
Carousel - only (3) blocks where power connects
Roof 3x2 - only (2) center blocks
All houses (excluding Pods):
Levee
All platforms:
Certain kinds of storage:
Terrain block

Currently, buildings can be stacked up to (34) layers.

Ground-Only

Some buildings cannot be built on top of another one, only on the ground.
Complete list of ground-only buildings:

Campfire
Dynamite
Irrigation Tower
All mines:
- Mine
- Efficient mine
Certain platforms:
- Metal platform
- Large metal platform
One kind of storage:
- Underground pile
Temple
Terrain block

Special Building Restrictions

Rooftop terrace cannot be built on the ground, only on top of another building.
Dirt excavator can be built on top of another building, although the drill part of the building should be above ground tiles.
Dynamite cannot be built on the lowest level of the map.
Levees, Dams and Floodgates can only be built on the ground or on another Levee.
Mine and Efficient mine can only be built on underground ruins

Faction-Specific

Factions not only have different building models creating a unique look, they also have unique buildings that can be built exclusively by that faction, creating specific gameplay mechanics. All types of faction-specific buildings, organized by menu group:
