You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

Thank you roj leather and Simon for your recommendations. I like the hanging chair and the almanda creeper on the wall. This will certainly liven up the patio.

How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

the 9' ceiling height will definitely help you with this. Here's what I would suggest (not knowing how far the side window is from the wall with the door on it: Use the wall with the door as the bed and closet/storage area. Build a closet, and put a loft bed at the top. Because it would have to be custom built, you can decide how high it is or how much storage you need. Kind of like this: [houzz=] or this: [houzz=] Can the space below the back window become a desk? And or/build a desk there with storage flanking it. Keep in mind that this isn't a very large room, and he'll probably want as much floor space as possible (at least my 8 year old does!).
