The proposals for Eastside City Park, submitted by six practices, have made it through to the second round of a design competition launched last March.
An interview process was staged in June and the six firms chosen were Broadway Malyan, Camlin Lonsdale, Gillespies LLP, Gross Max, Gustafson Porter and Patel Taylor.
The designs will go on public display next week, giving people a chance to have their say on their favourite, as well as answer questions on which features they think are important and how they would use the park.
The designs will then undergo a technical assessment, followed by a final judging process by an 'expert panel', expected in November.
Cabinet member for regeneration councillor Ken Hardeman said: 'Eastside is a key component of Birmingham's ongoing renaissance, and the park is a key component of Eastside.
'So it is vital that we deliver a park which is exciting and inspirational, a park for the 21st century, which will become a landmark and enhance our reputation as an international city.'
Funding for the park all depends on the council's success in the Big Lottery Fund's Living Landmark scheme.
The local authority has made it through to the second round but still has some way to go to secure a possible £50 million.
