Structure

Colonists can build structures of a various materials, each with different beauty, flammability, and hit-points. Enclosed areas will automatically prompt colonists to build a roof unless you apply a no roof region, or if the structure is too large (over 300 cells). Structures leave ash on the ground when burnt.

Walls[edit]

Main article: Wall

Walls are impassable structures capable of supporting a roof. Walls obstruct a pawn's line of sight, though pawns can lean into a free space next to a wall to fire at enemies from behind cover. Walls obstruct the spread of light, enclose rooms for temperature, cleanliness, beauty and other mechanics. They can be made out of any non-textile building material. Power conduits may be constructed inside walls to remove their beauty penalty. Smoothing natural stone walls allows conduits to be placed beneath them. Walls require 5 materials to construct.

These cannot be constructed, only mined, but act largely like walls and are provided for comparisons sake. All natural walls have negative beauty.

Smoothed walls[edit]

Smoothed walls are created from natural stone walls. Pawns assigned to the Construct work-type will smooth natural stone walls and rough stone floors designated for smoothing via the Smooth Surface order (Architect tab>Floors.) The pawn stat Smoothing Speed governs this task and is dependent on a pawn's Global Work Speed, Construction skill, Manipulation and Sight. Natural stone walls have a beauty penalty, while smoothed walls increase beauty and wealth. Smoothed walls despite having the same HP as natural walls, can be fully repaired by pawns assigned to Construct. As such they are superior to natural walls as support structures for your colony.

Material	HP	Work Required	Flammability	Beauty	Value^[1]^[2]	Cover Effectiveness
Smoothed Granite Wall	900	6,500 ticks (1.81 mins)	0%	1	1 (20)	75%
Smoothed Limestone Wall	700	6,500 ticks (1.81 mins)	0%	1	1 (20)	75%

↑ Bracketed value is that defined in the defs, however as of the time of writing in-game the wealth increase of smoothing a wall implies that they actually have a value of 1 silver. Given the disparity, this may either be a bug or oxbow code.

Doors[edit]

Door[edit]

Main article: Door

Doors provide entry points through walls for colonists while still keeping out enemies and wild animals. Pawns manually open doors which causes a delay as they try to pass through, as opposed to autodoors which open on demand and allow faster passage. All doors are generally locked to hostile entities, including prisoners, raiders and mad animals. A door can be marked to "Hold open," which means the next time it is opened, it will stay open, and then all pawns can pass through. A door can also be marked "Forbid". Colonists and tamed animals don't use forbidden doors, even if they're held open. However visitors, traders, and colonists on mental breakdowns ignore the forbidden status.

Autodoor[edit]

Main article: Autodoor

Autodoors are regular doors that open and close 4x as fast, but need to constantly draw 50 W of power. Lacking sufficient power, they lose the speed bonus and act like regular doors, until power is returned.

Powered autodoors made of stone open slightly faster than regular wooden doors. Powered autodoors made of any material other than stone open fast enough that pawns are not slowed down when passing through.

In all other aspects, an autodoor is identical to a regular door made of the same material.

Construction requires 30% additional work, 40 steel and 2 components on top of the 25 base material for the regular door.

For more info, see the main article Autodoor.

Bridge[edit]

Main article: Bridge

Bridges are structures that can be built on water. Bridges allow more rapid movement across water. Once built, they can support many structures, including wooden walls, but not particularly heavy structures including any other type of wall. Bridges allow for easier building in swampy biomes. Floors may not be built atop bridges.

Bridges cost 12 wood each. They can be damaged or destroyed by fire or explosions, including whatever was built on top.

Column[edit]

Main article: Column

Columns are passable structures which are capable of holding a roof which do not block sight, or movement and look quite nice. They have x/1.875 (.533x) of a wall's normal health, 4x the beauty, and 4x the value. They also have 25% cover effectiveness and do not slow down pawns. These were introduced in 1.1.
