Hi drmdilip -- While I waited for my trumpet vines to fill in sufficiently to provide summer shade, I sewed three matching striped shower curtains together, using the button holes on each end to tie it in place. I did this because as the vine was growing new, each thin runner would drop between the rafters rather than grow straight across. After a few years now, those thin runners have become a massed layer of thick vines, all of the new growth is straight up and by the end of summer I'll be able to easily remove my temporary support and have a roof of vines. It's not rainproof though -- for that, polycarb is practical, and I love the copper above!

plz send pic to relate better n glass or transparent acrylic sheets would do the job, giving justice to grass as well. glass n heavy stuff as roof on lawn is subjective to location space n relevance as it needs proper support n frame work. might come with alternative once actual site is known. plz send pictures. thanks shradha shah beescheese design

Hello Shivam Jain, You have good space for conversion of courtyard to living area but more we need space details like complete plan,site details with measurement then only we can set parameters.

I am not sure if this project is over, But try zinc sheet it looks great and gives you an industrial look.
