I wouldn't go the framless glass but a powder coated frame with top handrail and glass.
Might also be expensive to get rid of all that concrete unless you can find a good Greek family to give it to.
Just remember once you render and paint it will always require maintenance.
I presume you mean facia board to paint not eve as eve will be Asbestos.
I think all I would do is maybe upgrade the concrete balustrade to glass.
