They'll do so by extending the Anfield Road Stand.
Liverpool have confirmed plans to expand their stadium capacity to over 61,000.
Work will begin next week on adding a further 7,000 seats to the Anfield Road Stand.
The project, which was given planning permission in June, should be ready for the start of the 2023-24 season.
Andy Hughes, managing director of Liverpool FC, said:
“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.
“We needed certainty for this project to progress and are now in a position to be able to move forward. We began this journey in 2014 and are grateful to everyone for the contributions they have made to bring the project to this stage.”
