A functional room is a zone extending out from a piece of furniture that defines the room, created when the room is defined from that piece of furniture. A room, as the game understands it, is not defined by walls and doors. A chamber with a bed in it, for example, is not yet a bedroom; you have to select the bed and define a bedroom from it in order for it to be a room.
Everything covered by that zone is considered part of the room, and will contribute to both the room's value and its effectiveness. This zone does not need to extend to the walls. It is well possible to define several such rooms in one actual enclosed space; they may even overlap, although this comes at a penalty to the room's value. The maximum size of a room is 60x60 tiles.
To create a room, you must first have built something capable of supporting a room from the table or bed. Then you must select the completed item in question with the command and choose to create a room. The room's radius extends outward in a rectangle, but will stop when it hits walls or external doors. If you first build the door to create a closed space, then the game will define the room so you won't need to resize it unless it is very big.uild menu, such as a
If you want to have a door dividing a single, defined room into multiple areas without blocking the room's zone, you can set the door to "internal" in the door'smenu. Rooms do not have to be blocked off on all sides, and can even overlap, but for various reasons you will usually want to avoid overlapping rooms and give them proper boundaries.
In general, you only need to define a room from one object in the room. For instance, a communal dining room is defined from one table -- just give the room a large enough radius to cover the whole space.
Rooms can not span z-levels; when you define a room it can only be on a single level.
Rooms can be assigned to specific dwarves. When dwarves have their own room, happy thoughts occur when they sleep in it (alternatively, unhappy thoughts can occur when they do not have their own room to sleep in). Also, most nobles require an assignment to a room.
If you assign two or more rooms of the same type to a dwarf, the value of the piece of furniture that defines the room determines which room the dwarf will prefer to use. For example, if you give a dwarf two bedrooms, the dwarf will prefer to use the room with the higher quality bed, regardless of the comparative quality values of each room.
You can assign rooms to dwarves manually or automatically. If a dwarf (who does not already have a room) is ready to sleep and there is an unassigned room available, it will be spontaneously claimed by that dwarf. Married couples will share a bedroom, with the exception of some nobles.
Most dwarves don't have high expectations when it comes to rooms. A communal dining room and a communal dormitory is enough for the general populace, though making the communal dining room high quality and giving them individual quarters will give them happy thoughts, helping to avoid tantrums.
Nobles, on the other hand, require rooms of a minimal quality, containing a minimum number of Furniture. Not meeting their demands will make them unhappy, and also make them not function at their full capacity.
Room quality is determined by the total value of the room's floor and walls, plus the value of any furniture or other constructions in room. If the floor area of two rooms overlap it decreases the value of each room, but a wall can be part of multiple rooms without causing a decrease in value.
Room quality levels can be viewed through the View Rooms/Buildings () command.

 Increasing room value
Making a large room, so that it has more floor and wall space, is an easy way to start out a high quality room, as is digging the room out of valuable stone like limestone or obsidian (to make a really valuable room, put it in a mined out magnetite cluster) or keep eye out for gem clusters. Once a room has been mined out, its value can be increased by smoothing and engraving the floor and walls.
Afterwards, placing valuable furniture (Preferably encrusted with gems or artifact quality) is an option for increasing value, but not the only one. Constructions (including workshops) inside a room increase a room's value, so you can use non-furniture artifacts in a construction to increase room value:
|Barrel||Dyer's shop, Ashery|
|Bucket||Dyer's shop, Ashery, Well*|
|Mechanism||Lever, Gear assembly, Trap, Well*|
- * - gains additional quality from skilled architecture and construction
weapon traps are an excellent way to increase room value while being conservative with space: One trap can contain 10 valuable components plus a mechanism, all of which can be encrusted with gems.
Also, Levers have the special property that they can be used to stack an unlimited number of mechanisms, all of which count towards room value, in one tile. To add mechanisms simply link the lever to a deconstructible building such as a cage and pull the lever — one of mechanisms used for the link will remain in the lever. You can repeat this process as many times as you want until you increase the room's value to the desired level.
