Work is under way at Carrow Road to add extra seating to the stadium in time for the Premier League season.
A new row of seats is being installed at the front of the Barclay Stand lower tier, with small pockets of seats added in other parts of the stadium.
About 150 extra places will be available as a result of the work as the Canaries try to accommodate as many fans as possible for top-flight football.
City have also had to relocate about 30 supporters in the Jarrold Stand because they are obliged to provide additional commentary positions.
Last summer City extended capacity by 1,000 to just over 27,000 for Championship football.
