I wanted to reply with something funny, but actually there's a really obvious reason for the different architects to come up with all these.. weird i-want-to-become-a-meme designs.Build it as was, set up various apprentice schemes, masons, chippies etc.
Get some good from it.
They want to use the chance to put their stamp on it.
That's quite carnivorous, if you think about it.
If someone actually just redesigned it the way it was.. modern architects...
