If you have the privileges to create a build area, you can also delete the build area.
NOTE Once the build area has been included in a checked-in build configuration, that build area can no longer be deleted. If the build configuration has not been checked in, you can detach the build area and then delete. If the build configuration has been checked in, you can also delete the entire build configuration.
To delete a build area:
From the Dimensions Administration Console, click Area Definitions.
Place a check mark next to the build area you want to delete.
Click the Delete icon. The Delete Area dialog box appears.
Click OK to confirm the deletion. Dimensions displays a brief confirmation dialog box, and refreshes the list of build areas.
