The redevelopment of Liverpool FC's Anfield stadium is expected to be ready in time for the 2023-24 season.
Plans to increase the capacity of the stadium to 61,000 by adding 7,000 seats to the Anfield Road Stand were backed by councillors in June.
The build will take place throughout the season while matches continue to be played throughout.
Andy Hughes, managing director of Liverpool FC, said the club was now in a position to move forward.
"We have been clear from the beginning that in order for this expansion to go ahead we needed the co-operation of local residents and the community, to successfully navigate the complex planning landscape, and to ensure the project is financially viable," he added.
