Plans for Waterloo's riverside gardens started in 1936. Jubilee Gardens was finally opened in 1977 but was then used as a spoil heap by London Underground throughout the 1990s.
WCDG worked with other local organisations to get a new plan for the gardens approved in 2006, but this has been blocked by legal problems and a lack of cash.
Southbank Centre (which currently manages the land) has been working in recent months with the architects to revise the plans and reduce the impact and cost.
Dutch designers West8 want to hear your views before a planning application is submitted in October.
