Plans to redevelop Villa Park have been given the green light by councillors in Birmingham.
An extra 7,400 seats in the North Stand will bring the total capacity up to 50,000.
A new club shop and academy building will be built along with upgraded hospitality facilities.
Work - including demolishing the North Stand - will begin next year, although councillors raised concerns about parking and transport.
Improvements to Witton Station are planned, funded by the West Midlands Combined Authority, and transport chiefs are looking at making trains more regular and improving access for passengers, the Local Democracy Reporting Service said.
