Ok, to play devils advocate (only slightly though) is it only me that thinks this is all a bit silly ?
This is a 30yr old "work", i say work because it's not art is it, i can't personally determine what i'd call it but for me it's not within the remit of this site. If there's a chance this could jeapordise 250m quids worth of local investment in somewhere where it sounds like it's badly needed then i'd have no qualms relocating it. I've a self built circle in my garden, but if i move out should the next owner have to preserve my 5 year old folly ?
(Sorry Paul ;) )
