Barcelona's city council has approved the next phase of its superblock programme, with six new 'superilles' planned for the Eixample district by 2027. The expansion will bring the total number of transformed intersections in the grid-plan neighbourhood to 21.
The superblock model, which restricts through-traffic on interior streets and converts intersections into pedestrian plazas with trees, benches, and play areas, has become one of Barcelona's most internationally studied urban planning innovations.
Results so far
Data from the first completed superblocks shows a 25% reduction in nitrogen dioxide levels, a 30% increase in pedestrian traffic, and a measurable decrease in noise pollution. Property values within superblock zones have risen an average of 4% more than surrounding areas.
Opposition
Not everyone is convinced. Local business associations in some affected streets report initial drops in footfall during the construction phase. Delivery logistics remain a challenge, and some residents object to the loss of street parking.
