Editing 40d:How do I increase the value of a room

Digging a room within a layer consisting of [[obsidian]] or [[flux]] will inherently give it a higher value than a room built inside a mundane stone such as granite or gabbro. Additionally, veins or clusters of precious minerals (whether [[ore]]s or [[gem]]s) which pass through the room can provide a dramatic boost in value.

[[Room quality]] can be increased by [[smooth|smoothing]] and [[engrave|engraving]] the walls and the [[floor]].

Constructing floors in a room using high-value building components (such as [[aluminum]] or [[platinum]] bars, or perhaps [[soap]] made from [[megabeast]] fat) can dramatically increase the value of a room if its location is important but valuable stones do not occur in the region. Note that constructed floors cannot be engraved, and constructing a floor on top of an existing engraving will destroy the engraving, resulting in the usual consequences of [[engraving#Art defacement|art defacement]].

Any [[Furniture]] (such as [[statues]], [[chests]], [[cabinets]] or anything listed below) will increase room value.  If made out of a material that the dwarf who owns the room likes, they will perceive the room as more valuable than its listed value, and be [[thought|happier]] for it. For instance, if a dwarf likes [[copper]] and/or [[armor stand]]s and you put a +copper armorstand+ in the room, she may view that as a *copper armorstand*.  Whether this would be better than a +gold armorstand+, which would simply hammer room value without the increased perception, is in doubt.  Dwarves that do not have such preferences perceive the room at its base value.

[[Lever]]s count as furniture for the purpose of increasing room value, and an unlimited number of mechanisms can be connected to a lever simply by linking it to an object and subsequently deconstructing said object (either directly, or by simply pulling the lever if the object is a [[cage]], [[restraint]], or [[support]]).

Weapons not being used by your dwarves (whether due to your military structure or due to the weapon being inherently unusable) can be placed in weapon traps, and traps located in a room will increase the value of the room by the value of all components. A trap containing an artifact weapon can easily max out a room's quality. This works for both conventional weapon traps and upright spears. As an added bonus, a strategically placed menacing spike in an annoying [[Noble]]'s room can also be employed for the purpose of arranging an [[unfortunate accident]].

[[Cages]] add the value of the animals occupying them to the room value, and you can store unlimited amounts of animals in one cage.

[[Coffins]] not set to burial are not considered rooms and so can be built in other rooms without decreasing that room's value. This takes up space, but you do have to put the coffins somewhere anyways. You might as well get value from them.
