Ye gods and little fishes.
Looking at the end wall, I think you'd have to have custom glass cut to fit if you broke that.
All in all, that's one HUGE load to shift. Do you have a truck that size? You probably need special access equipment to take it down safely, too.
Also, being that big and weighing that much, it would need some serious foundations, enough to justify hiring a digger and getting a cement truck round to pour them.
You sure you wouldn't skip the glasshouse and take a month's holiday around SE Asia or hike the Andes or something cheaper and easier like that?
Then again, if you've got a garden big enough to justify that thing you're not that worried about money, are you? Hmm. I could take out the washing lines, throw the old one, give away the newer one, take up the lawn*, dig trenches, lay foundations, lay a perimeter path, put in a 12m-square glasshouse, stretch a few washing lines across it to dry stuff even on drizzly days, grow fruit and veg and have some sofas and coffee tables out there for lunches. Not sure the people on the ground floor north of it would appreciate that, but it'd be nice.
* The entire lawn.
