The top prize at the Venice Biennale went to a project featuring La Torre de David, the abandoned skyscraper that was invaded by squatters. "Squatters" who now live in the unfinished tower structure have created a vibrant community.

The firm Urban Think-Tank studied the building and its inhabitants for one year, documenting how people have managed to create this functioning living environment without elevators, infrastructure, electricity or income.

Inhabitants created their own personal units and have established a number of small businesses in the tower, including nail salons and a rooftop fitness center. Community spaces include television rooms, basketball courts and even a few churches.

The tower, which has been called a vertical slum, is the subject of the book Torre David: Great Skyline, which provided images for the exhibit at the Biennale.
