Barcelona’s urban layout of “superblocks” has proven to be a great way to make cities liveable, efficient, and environmentally friendly. We’ve looked at the brilliant design in Barcelona before, and now the question is how to take this urban design to other cities. Can car-focussed cities like Atlanta, Toronto, and Sydney benefit from the person-focussed approach in Barcelona? Of course they can, and so can other places like Mexico City and Zurich. The question how to implement the design approach and at what scale.

We’re all one step closer to living in a 15-minute city.

“Density is important, as the superblock model focuses on districts where many people live to allow active street life,” says Eggimann. Having enough people in one area also makes public transportation efficient, he says, and good public transportation is part of what makes the superblock possible. The design doesn’t work well in sprawling neighborhoods that only have single-family homes—even if those neighborhoods have a perfect street grid, as is the case in Atlanta and many other American cities.

While cities are taking a variety of approaches to rethinking traffic on streets, Eggimann thinks that superblocks can be especially useful. “I think the superblock model is particularly interesting as it strives for combined tackling of multiple challenges neighborhoods and cities are faced with—mobility, noise, walkability, urban green space—and that it is a model which envisions city-scale wide and broad transformation, going beyond single street transformation,” Eggimann says.
