I compared the map of the project plan ( http://www.templefarmdevelopment.co.uk/current) with the areal photo in Google you can clearly see that the project area is indeed a "one piece - compound" on which a body shop (R.P. Autos- Temple Farm Ind Est/Ship Rd,Chelmsford CM2 , car scrap heap, vehicle dismantlers, small workshop garages an other things are residing. This body shop would now already be closed.
From above you see further that the other surrounding grounds belong to farmers because the grounds are farmed, what makes this rumour implausible
What remains is satire ...Imagine these farmers would have become suddenly rich and now be making holidays together with the owner of the body shop on a distinct island which will soon not exist because of the climatic change everywhere and rise of the sea level. They would not envy the witnesses who donated for their holidays and gave their last money and not envy those poor bethelites that would soon be jobbing at Temple farm for the slave, at sweat jobs for slave salaires but in beautiful landscape. "We have drawn the better lots anyway".
