SUPERBLOCKA: Reclaiming Our Cities from the Hood of the Automobile
The modern metropolis is facing an existential bottleneck. As cities grapple with skyrocketing carbon emissions, persistent noise pollution, and a glaring lack of recreational space, urban planners are forced to ask a radical question: What if we designed cities for citizens instead of cars? The answer lies in SUPERBLOCKA—a revolutionary framework in urban morphology that reorganizes existing city grids into localized, human-scaled havens. What is a Superblock?
A superblock (known locally in Spain as a superilla) is an urban design strategy that aggregates a small grid of city blocks—typically a 3×3 square of nine blocks—and restricts through-traffic entirely to the outer perimeter.

By pushing heavy transit, buses, and cross-town freight to the exterior boundaries, the internal corridors are transformed. Inside the SUPERBLOCKA, the traditional asphalt layout changes fundamentally: Speed limits drop to a maximum of 10 km/h (roughly 6 mph).
Curbside parking is phased out or moved completely underground.
Through-traffic is prohibited; only emergency vehicles and local residents can enter. The Triple-Bottom-Line Benefits
