Speaking from experience Lewisham Planning do not respect the UDP or planning framework, when they want to push a development through so what difference does this make. Lewisham planning & Lewisham council have become a rogue council, making decisions that only take into consideration the bottom line of the developers and quite frankly not considering the local population.
I don't work for Lewisham before anyone starts, but I would be interested to see any evidence that you have of this.......examples of applications etc etc. Accusations need to be backed up with the right evidence, otherwise its libellous....
