Project summary

Edit project overview to modify the project summary.


The vision of the project, was to reduce crime and fear of crime in order to increase use and enjoyment of the river and its surroundings. The aims were to create new community open space called Cornmill Gardens near Lewisham town centre and to create a new river channel, meandering through the middle of the park Ladywell Fields.
