By Train:

The journey time from Victoria is 25 minutes. You can also take trains from Waterloo and change at Clapham Junction. Turn right out of the station car park—BedZED is about 8 minutes walk on the right hand side—distinctive wind cowls visible on the roofs. 3

Food Growing (2007) 28 households, (39%) of the 71 questioned, grow some of their own food but the extent varies from a few pots in the sunspace to a council allotment. This is lower than the average in Hackbridge of 46%. Of those 28 households at BedZED, 20 use their gardens, ten use the on-site allotments and one has a council allotment!
