I think the NIMBY objection is to any housing on the site not to an actual number, If I was cynical I would expect 350 to be rejected on appeal then 250 approved on a subsequent appeal if they splash some more cash, the refusal grounds are a bit thin IMHO:

Oh dear, from that article "The committee also had reservations about the amount of money being put forward by the developers to pay for the education structure in the village, citing that the numbers of pupils would increase by 25 per cent.". I have personal experience along that line, I bought a new house in a similar size development in a small town in Dorset. The developer I have heard gave several £m to the council in the deal which was supposed to go towards funding a new school, something locals have been campaigning on for years. The council then claimed that pupil numbers were OK and therefore the money was subsumed into their budget from whence it has disappeared aka spent. Now I hear that there is pressure on pupil places again and we did indeed really need a new school just as locals have been saying for many years but there is no money. One can imagine just how angry some people are over all this development shambles but from what I have heard, in my area, it is pretty much all down to the council and planners.
