How might we meet the demand for ‘GROW-YOUR-OWN’ within dense urban areas where available land is scarce?

As part of the London Festival of Architecture What if:projects promoted the use of vacant, neglected and undefined spaces in the inner city of London for the production of vegetables. The team travelled a grow bag through London's square mile, placed a tomato house in the shape of Canary Wharf next to the Building Centre in Store Street and constructed a grow bag installation on Hoxton Square.
