Skyscrapers not only define a city's skyline, but they provide office, living and sometimes retail space to thousands of people in a city.

In a place like Mexico City, historic value is placed on architecture, and buildings have height codes restricting buildings higher than eight stories in order to keep the skyline intact.

So when there's a need for a massive building to help revitalize the economic center square of Mexico City, Zocalo, the only way to build is down.

That's where Earthscaper—a new design plan for an inverted skyscrapercomes in.

Designed by architecture firm Bunker Arquitectura, Earthscraper is an upside-down, 65-story pyramid with its center hollowed out so every floor can have natural light and ventilation.

On the top of the building there will be glass placed above the hole to preserve the concerts, culture gatherings and other activities that typically take place in the square.
