Hargreaves Associates has joined forces with LDA Design, the firm responsible for the capital's Gunpowder Park and Blackpool seafront, to develop detailed plans for the Olympic Park.
The Olympic Delivery Authority (ODA) this week announced that LDA and Hargreaves would develop detailed proposals for the park, which would be put forward for planning permission in September.
Allotments, meadows, wetlands and wooded valleys are among potential areas planned for the park, along with river walks, natural amphitheatres and lawns. Also among the planned areas are new wildlife habitats and cycle and footpaths.
LDA Design partner Andrew Harland said: "The Olympic Park is the UK's most significant landscape project in years and will have a positive economic and social impact on the area while also demonstrating exemplary sustainability."
A collaboration of London-based design firms will be working with the team to create a diverse green space that will feature a vibrant mix of leisure activities and enhance the park's ecology and biodiversity.
BBUK, Kinnear Landscape Architects and Sarah Price Landscapes will be involved in the design.
Garden designer Sarah Price said the Olympic Park was the largest project she had worked on to date, and she was awaiting further information of what her role would include.
Kinnear Landscape Architects practice principal Lynn Kinnear said the firm, which won a Royal Institute of British Architects medal and was shortlisted for the Stirling Prize for its design of the Walsall Art Gallery Civic Square in 2000, was excited by the project.
Kinnear added: "It is very exciting and we feel confident of our abilities. Everything is up for grabs at the moment and there's a lot of negotiation to do; the next one or two months will be an initial assessment period."
