What you see from below in this view are openings, ones on the left are interior openings while the ones on the right are openings in a roof soffit extending out over an outdoor deck. there is a single, very large skylight that lies over all these openings, mounted on the roof. There is a weather barrier that is concealed, that separates the exterior from the interior openings and seals to the bottom of the skylight at its mid section. If you go to my website at this page and look at the cross section at the bottom of the webpage, you will see this skylight detail.

Can you also please share the manufacture for the skylight?

It was custom-made and it's double glazed with an aluminum frame. So you should find out who does that kind of work in your area and also in your jurisdiction there maybe requirements regarding insulation values and that will affect the types of frames that can be used etc. this was in San Francisco.
