Buildings represent the infrastructure of a planet and facilitate the production of resources, construction of units, and advancement of technologies.

Prior to construction of the Terraformer, every planet has a defined finite number of fields on which buildings can be built.

Buildings cannot be destroyed in attacks, unlike defenses. However, all buildings (except the Moon Base and the Terraformer) can be demolished.

The construction time of buildings can be reduced by upgrading the Robot Factory and Nanite Factory.

Construction time in hours: (Crystal + Metal) / (2500 * (1 + Robot Factory level)) * 0.5 ^ Nanite Factory level
