Students Josh Engwerda and Leyla Acaroglu will operate businesses from the pillars after winning the City of Melbourne City Pillars Challenge.
They will transform the pillars, which previously operated as newspaper kiosks.
Engwerda, of Melbourne University, said he would target inner city residents, offering a Green Wall Garden product for urban dwellers.

Acaroglu of RNIIT said she would create a retail space for local eco-conscious designers and artists.
Engwerda will use his pillar, on the corner of Swanston and Collins streets, to sell a hydroponics system that quickly grows plant crops.
He said the product, an alternative to conventional gardening that can deliver up to 90 per cent water savings, was perfect for dense urban environments including high rise balconies and rooftops.

Engwerda hopes to sell other products including seduberries, head-shaped strawberries. – SHANNON DEERY
