For a small structure like that, structural glazing is possible and is obviously what is being done there. The glass is more than capable of holding itself up and together with structural silicone joints in that tiny thing. Glass has a higher modulus than steel. It's just very brittle.

gwharton - Look at the second image. I don't think it's very small.
I'm not sure what modulus you're specifically referring to for the glass. Modulus of elasticity? Could you clarify?

From the standpoint of material strength and deflection, that thing is tiny. It would only need a secondary support structure if there were intermediate panel joints interrupting vertical continuity. Those are the weak points. Since the glass wall panels are continuous from floor to roof, and the wall span is not really long enough to have un-braced intermediate wall segments, it doesn't need any other structure than itself.
To be honest this strikes me as a design-assist build with whoever is manufacturing the glass system. So they likely have structural considerations pretty well hidden into a proprietary series of glass connections. My guess would be a rigid moment connection hidden in the ~6" black base, and you can see the glass fins acting as a portal frame to the opening on either side. There's also a pretty large clip evident at the middle of the header, which is directing the center load to the two fins on L/R of the opening as mentioned. Its spanning back to a similar clip anchored into the building.
How is the glass on the door beam installed? Won't it fall down? It looks like there is no supporting structure underneath. Structural glass

yes please
Yep, that totally looks like a well thought-out design.
It looks like something.
OP - there is not structure in that thing. Just the aluminum frame holding up the glass.
There are glass fins and some spider clamps, but there is also plenty of caulk.
Structural calk.
