Already you have left space for 18mm thk single glass.. to insert inside the hollow gap.. A;so a electrical wires in been kept on top, i dont know how u where u wanna used that for, there is no sandwich type glass space over there... Wood u hav already used for panelling & u r looking for glass.. wat type to take... My suggestion will be, u go for clear toughened glass, so that on one side u can fix film, ,,, so that any time if u feel like to change the design u can. but if u for for designer glass or decorative glass, which will not alter later, that will be one time large investment for u ,,, But changing the film will not disturb the entire partition and glass , only reasonable price u can change the entire film as per latest trendz

well for the garden, you'll have to wait till spring but, put some tall plants/flowers near the building and smaller ones near the street. Ex:lots of lilies(orange and yellow) near the building, then candytuft in the middle of the garden and finally some Thymus lanuginosus near the street.

AFTER CONSTRUCTION, THE PARAPET OF THE STRUCTURE IS NEEDED

The point is not with the glass,but with the curtains .i think that,curtains with that much height will not look nice ,so I m asking for alternative.I also thought of doing hatching on the glass,but curtains will kinda spoil the look.
