Silverstone has been forced to increase its capacity due to a high demand for tickets.
The Northamptonshire circuit announced on Monday that they plan to increase the potential attendance for the British Grand Prix by more than 3,500.
This comes in the wake of ticket sales being 10% up on the same period last year and will result in the creation of two new grandstands.
Silverstone's managing director Richard Phillips said: "We had fantastic crowds on all three days of last year's British Grand Prix and interest in this year's event has been even higher.
"Increasing our capacity will enable even more fans to experience the spectacle, excitement and drama of Formula 1 at Silverstone."
The British Grand Prix will take place on July 8.
