I was thinking more like B. however, rather than connect the string on the left side to that bottom corner, I think you would want it to connect higher. say, in your second drawing, the peak is point A and clockwise around are points B C and D. You have the string connected from B to D. I would suggest that instead, you measure from point A to point B, and let's say it is 40". Then the string should connect on the left side to a point E that is 40" down from point A. This way when you draw it back, it will lay the fabric fairly flat along A to B, and the rest of the fabric from E to D will taper down, like a jabot, along the B to C edge of the window. The reality is that you would need to have that A to E distance be longer than the 40" to accommodate the folds in the fabric as it stacks back. Actually I think it takes longer to explain than to sew! ;) Don't get turned off by this pic which is very country and your window deserves a much more modern look, but look at it only for the structure as it illustrates what I'm talking about. The lower you make point E, the more slack and drape you will get along the top...the closer you make it to that theoretical 40", the flatter it will lay. And remember too your top will be angled, not square like the picture so the amount of fabric that s blocking the window will be much less than in this picture.

I think the rod height is fine where it's at. Putting it at the ceiling won't make a difference. The worst part is they're too short. The other thing that stands out to me is, because the wall space is narrow, I'd remove the finials and just let the ends of the rod hit the walls and extend the panels out. I'm not a fan of mini blinds, but the fact that they're white looks fine.

I guess the lifestyle that it was assumed would be lived in this space is one that doesn't require privacy. It does not look as if those windows were ever meant to have curtains or shades. Perhaps you might consider a lightweight folding screen of some sort that could be used and easily moved where ever it needed to be. Just a thought. I am not exactly sure what the configuration of your space is, but it certainly looks to be problematic for putting up privacy blinds. Maybe you need a different approach. I suggest the folding screens that can be used or folded up out of the way. They would be independent of the windows. On the windows you would really need something that is held tight to the window. Beware of those shades that reflect light and heat back outwards. They can build up enough heat between the glass and the shade to do some damage. I have heard stores of the glass exploding in some instances where there is a double glass layer. And, it looks like you have an awful lot of hot sun to deal with, an awful lot! You are living high up in the sky where the sun is! That is the stark reality of it. That looks like a building design that might be more suited to a cold climate where the hot sun would be welcomed. It might be nice if you lived in Sweden, but, it looks to defy a good sense of what it means to live in a desert region like that. Sure that the previous generations built homes that were much more suited to desert living. Sorry, but this is an unnatural way of living that can only be sustained by artificial means of turning up the air conditioning. You have a problem without a choice of solutions because the choice to build and to live like this imposes limits. And, the design imposes even more limits. Previous populations built differently. I dont know about Bahrain, but I have read that some desert architecture of old incorporated cooling towers that invited air flow by channeling the prevailing winds, and overhead protection from the unrelenting sun and heat by the use of thick walls and overheads. They built thick walls close to the ground. To live under glass under the relentless sun seems to defy common sense. You are living in a solar oven powered by the intense heat of the sun! The only way to turn it off is to rotate the earth. Who ever built this tower to the sun was not realistically considering how it would be to actually use it and live in it. Sure that was not a consideration. You can't defy Mother Nature, or the universe. The elements will win, in the end, always. My best suggestion is folding screens.

I would have preferred the landlord would have at least provided blinds or curtains so that we could move And get settled first and not have to focus on the urgency of getting blinds so the entire neighborhood is looking in your house on a corner lot and spending hundreds of dollars after we just gave them all our money. It would have been nice to have had time to pick the stuff you want after got a feel of place after a few weeks 🤷🏾‍♂️
