Solar screen on the outside. I'm in coastal NC and we have screens specifically for summer made of this material. We swap out the screens in winter when we welcome the warmth of the sun. Makes a BIG difference. Our window guy explained that if you put it on the outside the window doesn't have a chance to heat up. Any of the big box stores sell it. https://www.google.com/search?q=solar+screens&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=sb

The first thing that strikes me is that your curtain rod is too short which is why you have to push the curtains to the side which kills the vibe in this room. Get longer rods and linen-type curtains that are fairly similar to the wall color which will give the room warmth without looking busy. Please make sure that your area rug is as large as possible because that will make this room look fabulous. Little bitty rugs do not. I would choose an Oriental rug in warm colors because it will hide little accidents, at least until you can address them. I would definitely get a sofa, so great for cuddling with your husband and kids. I would place it in front of the window for good lighting for reading but also because it gives you the best sight lines into other areas of your home. Instead of a coffee table consider a large ottoman with a lid so that you have plenty of storage space. Please don't buy a brown or black leather couch. They look dated and are so difficult to decorate around. Try beige or caramel, with two chairs in contrasting colors, perhaps a nice blue or green, colors that will be in the carpet hopefully. You can also use the carpet colors to choose pillows for your soft furniture. Find some nice pictures to put on the walls, a large green plant, a bookcase or two (books are a must in a room) and side tables for lamps. By now your room will look gorgeous and be pretty well furnished and, most important of all, will be comfortable and fun to be in.

What do you need to store? That would help determine what type of piece you could add. Adding two more panels to each window would be a good idea. They aren't quite full enough as is. I like this panel system from IKEA for sliders. https://www.ikea.com/us/en/p/yrla-panel-curtain-white-white-20378770/

Thank you @Patricia Colwell that is what I needed. And I posted a pic of the space not sure if you are referring to entire space. This was the only pic I could get from someone elseks home, so please bear with me. My home is still to be built this year. Here is a clear one without the measurements. The patio doors are in the great room, the kitchen is to the right and the other area with windows is the kitchen nook. All 12 ft ceiling, so I need something fairly coordinated, but the nook will have blinds/drapes. I just do not want verticals for the patio doors. I am really not crazy about sheers either but would consider. I suppose if I do sheers they will need to be at the same height the side drapes will be. Not sure I can do anything that would sit at the top of the patio doors, unless they are solar shades but I don’t know if those would look good, either.
