Sorry for that - I meant to put a load more into it but clicked on 'Submit' prematurely
I don't believe it was me who said it was impossible - just that there was a need to retain the cablenet.
My renders (which GX did say were close to the truth) always retained the cable net but assumed the newly raised roof would not be as high as what the final design has turned out to be and would snook in UNDER the cablenet at the front and thus wouldn't need anything like those two complicated contraptions which will ACTUALLY be supporting the new end roof (above the retained cablenet)
These renders were created November 2012
