Buildings are structures that are placed into the world for  Beavers and  Bots to build and use, and are the primary game mechanic that the player interacts with.

They are separated into 14 Building Groups, each dealing with a different aspect of the game. Each building group corresponds to a tool group on the toolbar. However, tool groups can also have actual tools that aren't structures.

Some special common Characteristics determine construction and usage restrictions. Certain buildings are also restricted by  Faction. Some buildings require  Power, and some need  Workers. Most buildings cost varying amounts of  Science Points to unlock. Most buildings require Goods for construction.

The majority of buildings that require  Workers may also unlock the ability to employ  Bots, at the cost of additional  Science Points.

Unlocking

 Science Points unlock new buildings. Certain buildings are available to build from the start. Check the Building List below for individual costs. Those with zero  Science Points cost are unlocked at the start.

Once  Bots are unlocked, it is possible to spend extra  Science Points to allow them to work in a building, with the exception of  Beaver-only buildings such as the  Power Wheel,  Large Power Wheel,  Inventor and  Observatory. See the  Bots page for more details.

Construction

Buildings require time and  Materials to build, except for:

•  Paths and the  District Center which are built immediately upon placing; and
•  Gatherer,  Lumberjack and  Scavenger flags which lack a material cost.

When buildings are placed, they appear as construction sites, allowing  Builders ( Beavers or  Bots employed at a  District Center or  Builders' Hut) to begin construction.

Buildings may be placed on top of any  Solid buildings under construction, excluding  Terrain Blocks. These buildings also appear as construction sites, but are not built until all buildings beneath them are constructed.

During construction, materials are brought to the construction site, and the site itself is worked on.

Materials

Each construction site has an inventory where required  Materials are deposited. Available builders seek the required materials in accessible  Storage buildings. They reserve then take as many of a single construction material as they can carry up to the remaining amount required by the construction, and deposit them at the construction site.

Construction Site

As more materials are brought to the construction site, more of the construction site can be built, with progress represented as a percentage bar.

The progress indicator increments in steps of 10% based on the quantity of required materials deposited that are committed to the building by a builder. Example: the  Observatory needs a total of 120 materials, so increases by 10% for every 12 materials deposited and committed by a builder.

Construction sites that lack materials display a  Construction lacks materials flag and this is added to the status messages.

Once all materials are deposited and construction progress reaches 100%, the building finishes construction and becomes active.

Construction sites can be (un)paused using the UI or a keybinding. The pause key is the same key that turns a building on and off.

Construction Order

The execution order of building jobs (both bringing materials and construction itself) is determined by the following factors. In reducing order of importance:

1. Sites that are turned off, inaccessible, or on top of other construction sites are not worked on.
2.  Terrain Blocks with another terrain block construction site behind its arrow-facing direction are not worked on.
3. Sites requiring a material unavailable in that District display a status message of "No construction materials available" and are not worked on.
4. Sites with higher construction priority are worked on before ones with lower priority.
5. Buildings are worked on in the order that they were placed.

As beavers can pass through building sites but not through most buildings, managing execution order is important, both to prevent unfinished buildings becoming inaccessible, and to prevent beavers from becoming  Stranded.

Notes: - When using the priority tool, setting the priority of a building also sets the priority of everything else below the building. For example, high prioritising  Wooden Stairs that are on top of a  Platform also causes the platform to be high prioritised. This does not happen when setting the build priority using the building's window.

Range

Builders must be at least adjacent horizontally. Vertically, they can only reach the block above them and any below. They can reach diagonally adjacent blocks even when the orthogonally adjacent blocks are occupied. Builders only sense work 10 blocks or less from a Path.

Buildings must be 10 blocks or less from a path

Demolition

Demolition can be done using the UI, a keybinding (N), or through the "Demolish Buildings" tool.

• It is not possible to demolish a building that has more buildings or paths on top of it.
• When demolishing a building, some of the resources will be returned back as  Rubble. This amount changes based on the difficulty selected.
• Demolition is instantaneous, even if the game is paused.
• Demolition is done using the N key, or by using Shift + N to bypass the confirmation page.
• When demolishing a building, a demolition confirmation window will open asking to confirm demolition of the building. Pressing Enter demolishes the building, pressing Escape cancels the demolition. The confirmation window also shows the amount of resources that will be returned in the rubble.
• Note that  Rubble does not count towards  Storage.

• On Easy mode, 100% of the construction materials are returned.
• On all other modes, 75% of the construction materials are returned. The number of materials to be returned is rounded up to a whole number.
• Builders will prioritise building over collecting rubble.
• If a  Storage building is demolished, all goods it contains are deposited in the rubble without any loss (regardless of the difficulty level).

Classification

Buildings can be classified by their Building Groups, by which  Factions have access to them, and by special characteristics displayed within their in-game descriptions.

Building Groups

Timberborn separates its buildings into 14 categories, with each group dealing with a different aspect of the game:

•  Paths and Structures contains buildings which facilitate  Beaver movement, as well as foundations for  Vertical Architecture.
•  Landscaping contains buildings used for manipulating  Fluids, the powered  Explosives Factory and  Dirt Excavator buildings, as well as  Terraforming.
•  Storage contains buildings used to contain Goods, such as  Food and  Materials.
•  District Management contains buildings used to manage infrastructure within and between  Districts.
•  Housing contains buildings where Beavers can meet their Sleep and Shelter Needs, as well as breed new beavers.
•  Water contains buildings used for the management of the  Water and  Badwater goods, as well as their respective  Fluids.
•  Food contains buildings used to farm and process crops.
•  Wood contains buildings used for forestry, as well as processing wood.
•  Metal contains buildings used for the harvesting and processing of metal from  Ruins and  Underground Ruins.
•  Power contains buildings which generate and distribute mechanical power.
•  Science contains buildings which generate  Science Points, along with buildings for producing and maintaining  Bots.
•  Leisure contains buildings which beavers can interact with to satisfy various Needs.
•  Decoration &  Monuments contain buildings which satisfy the Needs of beavers in their proximity, as well as some decorative buildings which serve no mechanical function.

Factions

Although both  Factions have access to most buildings, certain buildings are restricted to a specific faction, or have a equivalent for each one such as the  Efficient Farmhouse and the  Farmhouse. This is to give each faction a distinct theme, with  Folktails favouring comfort and nature, and  Iron Teeth favouring industriousness. This is also reflected in the shared buildings having distinct visuals for each faction.

Characteristics

Certain characteristics which are shared between multiple buildings are given their own keyword, styled in yellow, within their descriptions:

• Solid: Other buildings can be built on its top. However, not all of the  Carousel or  Roof 3x2's top can be built upon.
• Ground-only: Must be built on the ground.  Mining and  Domes have the extra restriction of being limited to their specific source block.
• Above-ground: Must be placed atop other buildings. Currently only the  Rooftop Terrace has this characteristic.
• Beaver-only: Only beavers are allowed to work in this workplace.  Bots are not allowed to work buildings with this characteristic.
• Requires haulers. Buildings with this characteristic require  Materials to function, but do not have workers to collect them. Without haulers to provide these resources, the building will not function.
• Wonder: The pinnacle of beaver technology. Each  Faction has their own unique Wonder, and building one to completion can be considered beating the game. Doing so on each map also allows you to start a new game on that map from any position.

Although the  Dirt Excavator does not have a special characteristic, it cannot be built with its drill directly above any other building, to any depth. Also,  Dynamites cannot be build on the bottom layer of the map.
