The plans for the redevelopment of the Town Hall and Olive Morris House, and the new Civic Centre on Brixton Hill will be considered by the Planning Applications Committee on 1 September.
Councillors who are members of the PAC will consider the plans along with submissions from the public, Historic England and other stakeholders.
As well as the new offices for Council staff and facilities for council functions like the registry office, almost 200 new homes are planned for the various sites.
Members of the public may attend the meeting, although only those who have made representations in advance will have the opportunity to address the Committee so that their concerns can be taken into account. The meeting takes place at Room 8, Lambeth Town Hall, Brixton Hill at 7pm on Tuesday 1st September.
