You could treat it as you would an open porch.

Here are some fun window treatment ideas, maybe just doing something fun and different with the windows would brighten it up:

Cute cafe curtains, or window film, hanging plants and sun catchers in either crystals for rainbows or stained glass ones to add color and design.

Colorful curtains. Light catchers. Stenciling on windows.

Plants, plants and more plants

Treat this room as if it had walls instead of windows. Add your furniture first to decide the layout that works best for you. From there start adding your plants, lighting and anything being used on the floor area. You will then know where you will need curtains or where you could hang art, pictures, etc. You can hang things right over the windows with suction hooks or stick on hooks. Hope this helps!
