In Aether Kingdoms, a basic set of buildings is available from the start. Additional buildings are unlocked through research. Among the possible unlocks are:
- Early game: walls, stables, production output buildings
- Middle game: district buildings, research bonus buildings
- Late game: endgame specialty and district buildings, more resource bonus buildings
You can view your current research in the account (right) sidebar.

Clicking on this widget opens the research page. Here you'll see the research tree and be able to select your current research. Once selected, you have to complete the research before being able to select a new one.

Research is performed by producing science in your villages. The science production of all your villages goes towards the research.
For each additional village you settle, the cost of each research increases by an additional 10%.
