megastructures
Enormous engineered edifices
Megastructures are enormous engineered constructions, typically on a scale far exceeding conventional buildings—think space stations, massive dams, or hypothetical concepts like Dyson spheres that would enclose a star.
The term often appears in science fiction and speculative engineering: The novel imagined megastructures orbiting distant planets.
In architecture, it can describe ambitious interconnected building complexes designed as unified systems.
