Via Humans Invent, an interesting proposal.
Burrowing down 35 stories beneath the heart of Mexico City, the Earthscraper defies everything the skyscraper stands for. It’s an ambitious rebuttal to architectural obsession with high-rise, so-called space efficient living. Shaped like an inverted pyramid, the Earthscraper will burrow downwards 775,000 square metres, preserving the existing city square above. By building below the city, the landscape above ground is left looking relatively unchanged. Concerts, open-air exhibitions and military parades regularly take place on the historic landmark above the Earthscraper, and it’s important to Mexico’s rich history that they continue.
