Buildings
Buildings form the foundation of every colony in Per Regna. They determine how efficiently a planet produces resources, constructs fleets, develops technology, and expands its influence across the galaxy.
Every colony begins with a limited number of construction slots and gradually develops into a complex planetary infrastructure network.
Buildings unlock progressively as players advance through the different Realms.

Building Categories
Buildings fall into several functional categories:
- Production — resource extraction and energy generation
- Infrastructure — colony management and development
- Lunar — specialized moon-based structures
- Advanced — late-game structures that reshape empire progression
Planetary Development Strategy
Successful empires balance multiple development paths:
Economic Expansion
- Mines
- Reactors
- Refineries
Military Development
- Shipyards
- Hangars
- Defense infrastructure
Scientific Advancement
- Research Labs
- Engineering facilities
Strategic Infrastructure
- Trading Centers
- Warp Gates
- Terraformers
As empires grow, planets evolve from simple extraction colonies into highly specialized strategic hubs.
