From Liquipedia Warcraft Wiki

Buildings are stationary structures that allow the player to increase and improve their army, gather resources and buy items. Most buildings are only available by construction, using a worker unit, but some are also available through other means, such as upgrading existing buildings or items.

Player Buildings[edit]

Constructable Buildings[edit]

The tech-trees of the four races all follow a similar pattern. Tier 1 allows for the construction of the Altar and the basic units building, as well as most of the support structures such as the food supply, shop, and tower. At Tier 2, two new unit production buildings are made available, generally split into casters and advanced fighting units. Finally, Tier 3 enables the production of a very strong unit from a dedicated building.
