You appear to have three rounded stone planters built into the stone wall outside the patio area. I don't know what is currently planted in them, but I'm guessing it may only be volunteer trees. I would turn the center one into a water feature to add a pleasant sound to your outdoor room. Then plant up the other two with flowers. As for the furniture, I would rearrange it with the sofa facing the outdoors side of the patio to enjoy the view of the wall and planters. Angle the two chairs opposite it. Move your two planters behind the sofa, flanking the slider, so you have flowers at both ends of the patio for everyone to enjoy. Close the tops of the two little metal stool/tables with lucite (or whatever came with them) and move one by each chair to be useful for setting drinks. Rescue your droopy string lights and put them on the tile roof edge. Add a coordinated rug and pillows in your favorite color. Anything can work with the neutral surroundings, and don't worry about the stone being too busy. Its background, so have fun with colors you love.

Then you should explain YOUR vision as best you can and see if we can help develop it further. What would help immensely is if you have any thoughts about the layout, that you show them in PLAN view (like bird's eye view) keeping it VERY simple with only the essentials shown ... no plants now except existing tree trunk locations. You need to give us someplace to start in our thinking or we would be lost and floundering. Start a drawing by enlarging the plot plan that came with your home at closing, or by measuring, or by tracing an enlargement of a Google Earth/maps print. Also, if your thoughts extend to views that surround you, I think you'll need to show what you see now. It is not helpful to see random individual pictures looking in various directions. Stand at the center of the outdoor living area, aim the camera outward and take SLIGHTLY OVERLAPPING shots that PAN from far left to far right of your view .... so we see the WHOLE space CONNECTED. Post the individual shots in order so they'll make sense. Don't try to substitute a computer generated panorama as it distorts and severely shrinks, eliminating too much detail. It's obvious if you follow those directions that much of your view will be obstructed by tree foliage. Ignore that fact for now. Additional pictures may be required later from a different viewpoint. We have to start somewhere.

FWIW it is worth to those looking at the options like Localeater. Did some research today. A 10x14 pergola starts at about 4k (pine) and goes up based on material and features. We like Walpole (have bought from them before) and they make a nice one in Azek (looks like wood but wears better ... we used it for new steps at our beachhouse) for 10k. The retractable sun shades for the top are another 2k. 8 weeks delivery, alas. Then of course we need the mosquito curtains, another 1k or so. We would also need to dig up our stone patio to put in a foundation, then the put the patio back and drill through it. Meh. An awning with Sunbrella is about $3200 for a 9x16 (that size would nestle in nicely near our koi pond area). 6 weeks plus. More expensive if it is retractable, but that kind cannot accommodate mosquito nets. The awning vendor had a product that was like a screen that came down at a push of a button, hidden up under the awning. That was another $10k though. Alternatively, you can use mosquito curtains. Not crazy about any of these options so far ... we might start simple with mosquito curtains for our french doors off the MBR in Maine and see how the y work. I like that we can get them in white...

In fact I love colorful exteriors that I would never have in my interior.
