Players may choose to contribute to Aardwolf by building an area. This is usually restricted to remort players, since they have experienced all of the game's mechanics and levels.

Areas are created online on a seperate copy of Aardwolf running on a different port. Characters are given a set range and the level and commands to create their area. The process of creating an area is a lengthy, difficult one; if successful, a builder can eventually see his or her original work become a permanent part of Aardwolf. Pre-made areas or areas taken from other MUDs are not allowed.

More detailed information on building is given on the Builder's Web Site. Applications for building are not currently being accepted.
