look for "arabesque" designs. 8 pointed stars, tesselated is a common one, as is the "moroccan lantern" look that's popular in tiles right now (that pattern started in persia, which is now iran.).

It looks like there are windows on the two walls adjacent to the fireplace, so I'll take your word for it that the TV can't go anywhere else. You make a focal wall by putting on it things you want to look at. I would clear the mantel, install built ins, get a lighter and bolder graphic rug, and pull the seating in closer. Before I did any of that, though, I'd see about improving the light. More lighting, or maybe just warmer color temperature bulbs.

hi chk I tried completing your living room . I guess the asymmetrical look of the living room needs to be combined together with some symmetry . 1. So you should get a big rug or 2 same rugs and curtain in same color lemon green or any other color of your choice . 2. you need to get 3 more peices of that lantern. one of same ht.used and 2 of a lil small ht. 3. you should get 2 lamps for the other side. they should be not small in ht. your one side have mirror so your window treatments and lamps will be reflected in mirror . 4. if you want to keep those table decor then keep it in centre and donot scatter it . also you don't have to keep all candles try to make a tray wid one or 2 candle and kettle's tc on main coffee table . for the other side a crystal vase with some green planters and flowers on 1 table wil look good.

Thanks for the suggestion. Yes, it definitely sounds like a good idea... just need to check on the cost factor, labor charges etc. considering the steep height of 3 walls, all together on all 3 sides. It would definitely cut down on water consumption & maintainance costs that would go with the vertical gardens.
