Adapting to Subterranean Architecture
"Mexico City is massive and famous for its urban sprawl, thanks in part to height restrictions forcing the city to grow out rather than up. There are also preservation considerations in play: no one wants to demolish historic old low-rise architecture downtown. In the face of these limitations, some designers have pitched unusual but provocative ways to densify the city without building skyscrapers. One such proposal calls for a 35-story subterranean groundscraper."
