I've been offered, & paid for, a small 2nd hand conservatory. The person who was going to dismantle it now can't. I can't let the seller down so I'm going to have to do ot myself. It's 3m by 3m. Pic attached. Can anyone advise HOW? Also how long it might take / how small it will break down to? Thanks... (niche Qu so hoping someone sees this today)
