And I think, BubblesBuddy, that you are missing my point a bit.
Yes, the rumour mill is obviously going, but that doesn't mean that it has any basis whatsoever in formal Planning activity.
As I've said repeatedly, there's certainly no harm in asking the official channels, but do NOT assume that they have an accurate picture of what's going on (or not).
For what it's worth - and I am absolutely NOT saying that it's necessarily the case in this instance - one of our standard tactics used to be to wind people up about affordable housing (the generally perceived views from the well-heeled older NIMBY's is that such housing will be filled with drug pushers, alcoholics and - God forbid - single mothers, and cause their property values to come crashing down around their ears), so that when we eventually pushed forward with an open market development of nice houses with minimal affordable provision, they were supportive (or at least didn't complain as loudly as they otherwise would have).
Similarly, one of the standard tricks I referred to at Public Consultations is to wind everybody up about affordable housing (and traffic volumes - that's another good one), so that off they go like clockwork mice and submit a raft of invalid and irrelevant objections that then obscure any real issues (so far as the Planning system is concerned, of course, affordable housing is a major benefit, and you need to generate city-centre-like volumes of traffic before the standard methodologies for traffic assessment flag any major problems).
Out of interest, you said your DH works on Planning for developers; what area of the country are you, and who has he worked for? I've worked at a senior level for or with quite a few of the major developers myself (Persimmon, Bellway, Bloor, Miller, Redrow, Hopkins, among others), so we may well have come across each other.
