Been meaning to flag this up for a couple of weeks:
Thanks to the work of Brockley councillor and London Assembly member Darren Johnson and other members of the London Assembly Environment committee, as of 1st October, planning permission is now needed for paving front gardens. The new planning laws respond to calls in the Crazy Paving report for legislation to control the number of concrete-covered gardens in London.
Paving over front gardens can cause drainage problems and flooding problems, has a detrimental impact on the environment and very often looks hideous. The report estimated that green space equivalent to the size of 22 Hyde Parks had been lost as a result of people paving over their front gardens, so it's great that the government responded to these concerns and passed this legislation.
