Mexico City Earthscraper by Bunker BNKR

The Earthscraper, designed by BNKR Arquitectura, is the Skyscraper’s antagonist in the historic urban landscape of City where the latter is condemned and the preservation of the built environment is the paramount ambition. It preserves the iconic presence of the city square and the existing hierarchy of the buildings that surround it. More images and architects’ description after the break.

The Historic Center of is composed of different layers of cities superimposed on top of each other. When the Aztecs first came into the Valley of Mexico they built their pyramids on the lake they found there. When a new and bigger pyramid was conceived and the Aztec Empire grew in size and power, they did not search for a new site, they just built on it and around the existing one. In this manner, the pyramids are composed of different layers of historical periods.

When the Spanish arrived in America and ultimately conquered the Aztecs, they erected their Christian temples atop their pyramids. Eventually their whole colonial city was built on top of the Aztec one. In the 20th century, many colonial buildings were demolished and modern structures raised on the existing historic foundations. So in a way, Mexico City is like a massive layered cake: a modern metropolis built on the foundations of a colonial city that was erected on top of the ancient pyramids that were constructed on the lake.

The main square of Mexico City, known as the “Zocalo”, is 57,600 m2 (240m x 240m), making it one of the largest in the world. It is bordered by the Cathedral, the National Palace and the City Government buildings. A flagpole stands at its center with an enormous Mexican flag ceremoniously raised and lowered each day. This proved as the ideal site for the Earthscraper: an inverted skyscraper that digs down through the layers of cities to uncover our roots.

The design is an inverted pyramid with a central void to allow all habitable spaces to enjoy natural lighting and ventilation. To conserve the numerous activities that take place on the city square year round (concerts, political manifestations, open-air exhibitions, cultural gatherings, military parades.), the massive hole will be covered with a glass floor that allows the life of the Earthscraper to blend with everything happening on top.

The Mexico City Earthscraper was inspired by the historic growth and development of the city, with each new layer built on top of another. Rather than a skyscraper, this earthscraper dives 35 stories deep into the earth in order to preserve the top layer of historic buildings in the main plaza, which cannot be altered due to federal law. The central courtyard would be converted to glass, which would filter light down through a central void to bring in natural light and ventilation.
