In RimWorld, your colonists are able to create buildings from the ground up. Structures can be made from a variety of materials, each with varying hitpoints, flammability, and beauty.
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 400 cells). As of Alpha 12 a roof can extend up to 6 cells from a wall, so interiors have a maximum size of 12 cells on the shortest side. This allows for 12 by 12 square rooms (14x14 including walls) or 12 by X rectangular rooms. Rooms built larger than this will remain unroofed (colonist buildings) or result in a roof collapse (mined rooms). Larger rooms can be built with the use of single-wall pillars.
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 auto-doors which open on demand and allow faster passage. A door can be locked by marking it forbidden. Colonists can't use locked doors. Visitors and colony animals can pass through doors, even if locked. A door can be marked to 'Hold open' so that the next time it's opened it will stay open.

Autodoors have powered operation to allow people to move through it without slowing down (with the exception of stone doors). They require a constant 50W charge to operate. A powered autodoor opens four times as quickly. An unpowered one acts just like a standard door. Autodoors have the same max hit points of a standard door of the same material. A powered door requires at least ~57.69% base speed to not slow colonists down, while unpowered doors require 4x that speed (which excludes all unpowered doors). Like standard doors, autodoors divide rooms for the purpose of bedrooms and ratings. Autodoors require 25 materials and 2 components to construct.

An impassable wall, capable of holding up a roof if the space between supporting walls and beams is not too far away.
Walls can be built out of any material and Power conduits may be constructed on an existing wall. Walls require 5 materials to construct.
