As part of Barcelona’s efforts to reclaim its car-congested streets for pedestrians, the city has tapped architects to create “superblocks” — groups of streets transformed into car-free public plazas. One such project was completed in 2019 by Leku Studio in the trendy neighborhood of Sant Antoni. Redesigned with attractive way-finding elements and street furniture, the Superblock of Sant Antoni is the second of six superblocks completed to date.

The Superblocks Program was conceived as a way to curb air pollution while addressing a lack of green and social spaces in the city. Each superblock comprises nine city blocks and is closed off to thru-traffic, with parking tucked underground. New street furniture, colorful graphics and removable planters are added to encourage walking, cycling and social gathering.

“Where previously there was an urban highway, now there is a healthy street full of life and green, where there was a traffic intersection now there is a livable plaza,” explained the architects, who implemented the first phase of the Superblock of Sant Antoni in 2018. “Car noise has been replaced by children playing, cheerful conversations between neighbors or elderly people chess games. The transformation continues together with this flexible landscape capable of integrating new changes derived from urban testing and social innovation.”

Reversibility was a guiding principle behind the design of the Superblock of Sant Antoni. As a result, the architects created an “adaptive urban furniture toolkit” so that the street furniture and planters — built with eco-friendly materials — could be combined in a variety of ways. The graphic tiles and signage also provide a reference for the arrangement of the new urban elements. The City of Barcelona plans to create 503 superblocks that will eventually connect to one another to create a series of “green corridors” that total 400 acres of new green space by 2030.
