Stairs landing finish for balustrade

[drArqon]

Hi, any idea what to use to nicely mask the subfloor-plasterboard join. So it looks tidy and nicely transitions to the glass balustrade subrail?

Where is the balustrade sole plate?

Won't there just be posts with the glass 'floationg' above the deck? Or do you have a base rail?
