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.

Privacy could be obtained with a screen, placement of potted plants, an open bookcase, but I like your idea for a curved track with a curtain as one option for visual privacy. I would rotate the dining table 90 degrees and move it towards the balcony. I would remove those two chairs/tables because the layout of a single chair that far apart from another chair does not work. You may need to move the seating away from the main entrance because it looks like you walk in and you're on top of a loveseat. In such a tight space with so many doors that open in to the main living/dining - my advice is to keep it simple. Scale the furniture properly and have pieces that are multi-functional. Example- an ottoman that can serve as seating. A bench at the dining table to seat 3 on each side. I would also place two smaller loveseats facing each other in front of the fireplace. This will give you an "entry area" (along the back side of the kitchen wall) and help to define the living from dining rooms. Even if you don't have a formal entry, try to create a bit of space to welcome people.

I think you should stay with a simple pattern for draperies. Possibly a pattern incorporating the white trim and warm yellow walls. This would be soft and understated and something that you wouldn't get tired of easily. Other colors could be introduced with accessories.

Most my doors were already here, but I did have one moved over, about 6 inches. However, the entire space was demo'd, and rebuilt, so that's not the best example to draw from. If you want the door hidden, in a pocket, yes, you will need a skilled carpenter. Essentially, the opening header and frame, will become twice it's size, with the "pocket" part, hidden behind the wall. The studs/supports will need to be removed to make a space for the door to slide into. Do you have any switches or outlets on the fireplace wall?
