I have been given an unused Galvanised Steel greenhouse kit. Made & Sold by NHM Ltd of Norfolk, ( who are no longer in business!). The instructions have been ruined by damp except for a tiny bit (hope to attach). I have contacted Norfolk Greenhouses but they are unable to help. It looks as though it was designed to be clad in PVC sheeting but I will change this to acrylic panes if I can get it assembled! I have spent hours on Google with no luck, except to find out that NHM are out of business. Any help gratefully received. Thank you.
