Woo hoo! Clever you!
I got mine from ebuygumbay, and would recommend:
Taking time to make good foundations
Having a patient and willing team visit to put it up
Get the frame up first, secured to the foundations, then on a windless day complete the glazing
If you leave it half-glazed, and not secured to the foundations, it will walk away in the next breeze :-[
You won't regret it SMP, looking forward to the photos 8)
