Door

Closed doors.

Open doors.

Doors can be constructed through the Wooden Building submenu within the Building menu (Alt + b). They allow the player and NPCs to enter a building without having to leave one wall unconstructed. They can be made from 8 boards and must be built between two existing structures, e.g. between two walls or fences.

Doors can be opened and closed with their respective commands.

Doors must be closed before they can be deconstructed.

A bug (confirmed in 3.13p4), allows doors to remove large rocks. By surrounding the rock with fences, then building and deconstructing a door on the rock tile, it disappears. This bug is still active as of version 3.32.
