An additional 1,000 seats for spectators and a first-floor concourse which will allow for a further 1,000 temporary seats are planned as part of the upgrade at Tollcross.
A further 2,000 seats were to be housed in a temporary enclosure at the north of the existing competition pool to meet the anticipated demand from people who want to see the world's top swimmers, including South Africa's Chad le Clos and Australia's Ian Thorpe.
It had originally been proposed that this would be demolished after Glasgow 2014 but Councillors have now decided to keep it to minimise disruption amid fears that it could jeopardise the legacy impact of the Scottish city hosting the Games.
"This will have a significant impact on every level of swimming programmes, from under-five classes to elite training and may impact on the perception of the legacy benefit associated with the Commonwealth Games," a Glasgow City Council report said.

Under the new plans, building a permanent extension at Tollcross, means that it will be closed to the public from only March to May next year.
It is due reopen to the public in October 2014.
The new plans are also a bonus for oganisers of the International Paralympic Committee (IPC) Swimming World Championships, which is due to be held at Tollcross in 2015.
