The Pepys Estate in Deptford, south London, will enjoy greater links with the River Thames, which runs alongside, as well as improved areas for play and nature.
BDP landscape architecture associate Martin Savage is working on the project, which aims to invigorate the housing estate. He said the scheme could set a benchmark for development in the area.
Although the estate has 17 separate green spaces, three are likely to benefit from the makeover.
"The three we think will go ahead are the ones that will make more exciting pieces of landscape design and start Deptford off on the right course," he said. "Although Deptford has a very cultural high street, the Pepys Estate suffers from its (poor) reputation - but there is a real naval history to the area, with a historic dockyard next door."
Upper Pepys Park, Lower Pepys Park and Aragon Gardens will undergo changes including an expanded nature reserve and more facilities for young people, as well as a specially designed kiosk.
"At the moment the nature reserve in Upper Pepys Park is pretty bleak and a bit of a security risk," said Savage."We will make it much more accessible and build on the idea that Deptford is a unique space on the River Thames.
"The bit of the park by the river will have a much more contemporary feel and stronger relationship with the river edge and Thames Path. People will naturally get drawn into the area."
A consultation has taken place with residents and more detailed designs are set to go out for public consultation soon. Tenders for work on site are expected to go out between August and October.
