22@ or 22@Barcelona is the Innovation District of Barcelona and it is the corporative name given to an urban renewal area in Barcelona's formerly industrial area of Poblenou, in the district of Sant Marti. Its aim is to convert Poblenou into the city's technological and innovation district, as well as to increase leisure and residential spaces. Centered on Placa de les Glories Catalanes, it is part of one of Europe's biggest urban regeneration schemes, begun during the 2000s and still ongoing, spanning 115 blocks or 198,26 ha.
The plan was approved in 2000 by the city council when the new 22@ land designation was introduced, replacing the 22a designation, used in industrial soil contexts. The 22@Barcelona model is already being applied in other areas of the city and is a benchmark in urban, economic and social transformation in cities like Rio de Janeiro, Boston, Istanbul, and Cape Town. It is a compact and diverse city that, instead of applying a territorial specialization model, employs a mixed model that favors social cohesion and fosters balanced and sustainable urban and economic development. At the end, the project will create 4 million square meters of constructed floor space, 3.2 million of which will be used for productive activities and 800,000 for housing and services.
Regarding subsidized housing, 998 units have already been built and 583 are currently under construction, for a total of 1,581. Regarding infrastructures, 14,800 lm of streets have been urbanized-of a total of 37 km-which equals 19,649 m2 of streets-with a high level of services, 46 new conducts, sewers, selective pneumatic waste collection, district heating and cooling system, 47,000 m of dark fiber optics, etc.
According to the last data on December 2011, an estimated 4,500 new companies had moved to the district since 2000, an average of 545 per year and 1.2 per day, although the most prolific era was from 2003 to 2006. Of the 4,500 companies, 47.3% were new start-ups. The rest moved from other locations. About 31% of companies in 22@ are technology- or knowledge-based companies. The estimated number of workers in the district is 90,000 (not counting freelance workers), 62.5% more than in 2000 for a total increase of 56,200 workers. Additionally, the global business turnover, not only of companies that carry out @ activities, totals some 8,900 million euros per year.
Since 2001, the resident population in 22@Barcelona has grown 22.8%, from 73,464 inhabitants to 90,214 (16,750 more people). This increase is 15% higher than the average for the city of Barcelona, which experienced a growth of 8% between 2001 and 2009.
