I think that what a described earlier, takes the process up to the 'Neighbour Consultation Expiry Date' and susequent Planning meeting.
It must have caused quite a furore, with a lot of objections, and the Planning Office had to go a stage further. This would be the Standard Consultation process whereby Statutory bodies, environment issue people, conservationists, etc would have been asked for their thoughts and reports; that gets us to Jan '19 I think.
