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
Doors separate rooms for the use of ratings and bedrooms. They require manual operation to use, and slows down colonists when they operate it. Doors always require 25 units material to construct.

Autodoors
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 requires 4x that speed (excluding 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.

Walls
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.
