Thanks for the interesting info.
Maybe a swine herdsman had a hovel there in 1340's then he died in Black Death and no one else has ever lived there. It would be intesting if a Councillor could comment on this matter please. I must assume the person paying GBP 250k for the land must have the nod from the council to build. Surely if no house ever there should NOT be permitted.
If we say it was a plague pit then they would have to have major investigations.
