Buildings are generally fixed, functional, player-controlled constructs. The role of buildings is generally to enable the production of units and/or unlock higher tech and function, although a few specialised racial structures are meant to contribute to static defense. Some Night Elf buildings can potentially be moved in Warcraft 3, but change or lose their functionality while mobile.
All buildings must be constructed on "buildable terrain", which excludes all "off-map" terrain, other buildings and units, and certain map features such as hills, trees and stone/paved tiles. Additionally, Undead buildings must be constructed on blight (except for Necropolis).
Upon the destruction of all of a player's buildings, a player will lose the game.

The Town Hall, also refered to as Main Building or Main, is the most important building. It is where workers bring the resources they gather, and it is where workers are produced.
In each game, a player begins with a townhall and 4-5 workers. These are the basic foundation blocks from which to build a base.
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.
