Barcelona FC officials have announced that 14 design teams are in the running to play a part in the €600m (US$670m, £436m) redevelopment of the club’s iconic Nou Camp stadium.

The competition is for two separate overhauls of facilities at the Nou Camp. These would comprise alterations to the main stadium and the redevelopment of the nearby Palau Blaugrana – an arena owned by the La Liga club.

For the New Camp Nou development, AECOM, Populous and BIG are among those listed, while for the New Palau Blaugrana, HOK, Wilkinson Eyre and HOK are included in the elite shortlist.

The plans would see the capacity of Europe’s biggest stadium increasing from 98,000 to 105,000, with work starting in 2017 and completion slated for early 2021.

Also planned for the remodelled stadium, which originally opened in 1957, is a new roof, which would be added to the current open structure, new restaurants with a view of the pitch, and a steeper bottom tier to improve visibility for spectators.

The larger Nou Espai Barça development will improve the entire campus, with further additions to the mixed-use development including an ice skating rink, new offices, parking for 5,000 vehicles and improvement of outdoor spaces surrounding the facilities.

The shortlisted teams now have to meet a November deadline for Palau Blaugrana submissions and December for Nou Camp submissions.
