Build plots are used in BFME 1 to construct buildings at the faction's encampment. The player clicks on the circle, a radial menu will appear the faction's structures, and the desired building will begin construction when selected.
BFME 2 Edit
In The Battle for Middle-earth II, Builders were introduced, and their function replaced the need for a base's build plots. This made structures able to be built anywhere, on appropriate terrain.
The factions' citadels in The Battle for Middle-earth became fortresses in the sequel, and each fortress has seven build-plots around the foot of its perimeter, at which the player may construct arrow tower expansions, siege-weapon expansions, wall hubs (for most factions), garrisons (such as Men of the West's Dormitory), or other special defenses like the Angmar's Dire Wolf Kennel or Mordor's Gate Watchers expansion.
