Install a conservatory under the panoramic skylight

I had the idea to have a panoramic roof window installed. Dimensions approximately 3-4m in width and ~3m in length.

Below it should be a kind of conservatory. A glass wall should be installed to the adjoining rooms. The roof window itself with all the possible frills you might need. Let's see what the premium version would cost... Exterior blinds, top sound insulation, top thermal insulation, electrically operated "of course," aluminum frame (probably no reasonable alternative). Maybe solar protection glazing, rain sensor, ventilation function. I am considering having the exterior blind installed in such a way that I can still open the window and therefore ventilate even when it is raining. That means the blind would have to be a few centimeters above the window, surely not a big problem?

The glass walls to the other rooms would probably only have to meet low requirements since these are already considered interior walls. That means the roof window or the room below is also a direct living space and not a balcony. So the glass wall is "only" for letting light into the adjacent rooms and room separation.

Despite everything, I would thoroughly seal the floor with liquid foil and then tile it floating. If it should ever rain in, hopefully, the water will remain in this basin... I could also heat the conservatory via the central heating.

Who among you has something similar or just simply such a large roof window? What would you say about heat protection in summer and thermal insulation in winter? How durable are motors for large roof windows; what about the blinds? Are these overall solid systems you can trust without worries? For example, rain sensors and heat protection from the exterior blind.

General experiences with large roof windows?

Personally, I have only experienced roof windows with technology from the 80s. Accordingly, I am skeptical...

To give an idea of what I roughly envision, in the living room you just have to imagine glass walls running around the roof window.

Which house is that supposed to fit - (I'm currently too lazy to scroll through your entire thread history to the bottom)? I think your window guy is currently googling what time the Porsche center opens :-)

Well, elsewhere that's called a [Wintergarten]. Shading etc. is nothing special there or rather mandatory. I guess 25k.

Behind large window areas it can sometimes be too bright, I have experienced that myself. Which film do you use to prevent this and at the same time have privacy protection? Ideally, the light dimming should only have a limit upwards and let through as much as possible otherwise. Is that already possible nowadays? €: I also know that it will cost money. But I can't think of anything more stupid :)
