The 100 designs from 21 countries submitted to a competition run by the Royal Institute of British Architects will be displayed around Vauxhall's riverside, railway arches and small parks.
Entrants were encouraged to take inspiration from New York's High Line - an historic elevated railway that was turned into a leafy urban park - to make green links along the river and through the parallel viaduct.
Chris Law, from the Vauxhall Vauxhall One Business Improvement District said:
"There is a lively variation of ideas and many reoccurring themes. Our aim is to help create a great public realm for Vauxhall."
On April 15, a shortlist of three, plus a student winner, will be chosen. The shortlisted four will be asked to submit more detailed proposals.
