Editing 40d:Floor

A '''floor''' is a [[map tile]] that creatures can walk on. A floor is formed:
# naturally, as the ground (typically [[grass]] or a type of [[soil]] or [[stone]]),
# by constructing walls (thus creating a floor on the level above), or 
# by [[#Construction|constructing floors]].

Floors enclose spaces making the tiles below them [[inside]].

== Construction ==
Floors may be built using {{k|b}}→{{k|C}}→{{k|f}}, then {{k|u}}, {{k|k}}, {{k|m}} and {{k|h}} to designate a rectangular area.  Building the floor requires either the [[Masonry]] skill (for [[stone]] and [[glass]] floors), the [[Carpenter]] skill (for [[wood]] floors), or any of the [[metalsmith]] skills (for [[metal]] floors).

Floors can be constructed on top of existing natural floors; this distinction is subtle but allows for 'paving' (not to be confused with building a [[road]]!). Note that designated constructions, such as stairs dug out of natural soil, can be floored over. Beware the possibility of sealing in your fort when paving your entry hall. 

Constructed floors:
* count as [[construction]]s and cannot have [[wall]]s built upon them.
* can have other types of buildings built upon them, such as workshops.
* can be [[irrigation|muddied]] and subsequently [[farming|farmed]].
* [[cave-in]] when unsupported, punching through any floor tile in their way.
* cannot be [[smooth]]ed or [[Engraving|engraved]].

== Risk of clogging ==
Underground, muddied constructed floors can have [[tower-cap]] trees to grow on them if an [[underground river]] has been discovered, just like muddied natural floors. This can wreak havoc on reservoirs if a tree grows where a floodgate wants to close or blocks a narrow access hall.

One method to prevent growth is to build a paved [[road]] over any muddy floors. This can be a good use for all that extra stone.
