Thank you all so much for your sympathetic comments and advice. Since posting on this forum, we have new information that our immediate neighbours on the other side were also not notified of the work, as neither were we. As advised by Planning Aid, the legal charity for planning advice, Southwark Council must grant immediate neighbours a consultation right on all planning permissions and have 21 days to respond. This is a legal requirement under the General Development Procedure Order, which Southwark Council did not fulfil in these case.? As the entire front of the property has been concreted over, it will significantly decrease the value of the two adjoining houses.?Therefore we are appealing to Southwark Council will seek to overturn the decision and remove the work. However, the person taking care of Coplestone Road for the Council has been less than helpful, saying she doesn't know anything about the planning permission, and was rude and impatient on the phone. The permission is also not listed on Southwark Council's website. ? We have found the council employee dealing with Rd to be unresponsive, impatient and downright rude. She said she knew nothing about the case and would have to consult colleagues. As you can imagine, it's difficult to accept something so wrongheaded. Nature is precious, and East Dulwich should be kept as green as possible! As suggested, we will contact the councillors listed. Thanks once again to everyone, will let you know the outcome.
