mega-structure
Vast architectural complex
A mega-structure is an enormous construction—typically architectural or engineering projects of exceptional scale like massive dams, space stations, or hypothetical planet-sized constructs in science fiction: The Dyson sphere is the classic mega-structure of speculative engineering.
The term emphasizes ambition and grandeur beyond conventional building.
Also spelled megastructure.
