Morphs into:

The Lair is a key building for Zerg technology. The Lair is the second tier of the Hatchery tech tree. After morphing from a Hatchery, the Lair can be further morphed into a Hive, provided the Queen's Nest has been built.

The Lair allows Zerg to build a Spire, as well as research the Lurker ability at the Hydralisk Den. Many Zerg strategies involve quickly upgrading to Lair tech to access these units. Lairs are sometimes morphed in the natural, rather than the main base, to hide rapid tech development from enemy scouting (e.g., Comsat Scans.) Obtaining a Lair also allows research on several key Overlord upgrades, increasing their usefulness and survivability on the battlefield. In addition, the Lair allows the unlocking of level 2 upgrades at the Evolution Chamber and Spire.

Morphing a Hatchery into a Lair will increase the Hatchery's health by 550 points. This does not affect Larva production or resource mining.
