This is wonderful how you opened the stairs - you get a real sense of the architecture and it brings in more light. I applaud what you have accomplished. I'm going to assume that the wall above is patched with quickcrete and the whole thing is painted (try to get the wall beyond under the stair too). If you have / want a flat screen, you might mount a swing arm wall mount for a flat panel television on the vertical wall element remaining on the right - just about 3' - 3 1/2' (around 1 meter) above the floor so that it is eye level when you are sitting. The swing arm support will allow you to tilt the television away from the wall ever so slightly across the nearby corner. This can help to eliminate glare from the nearby window and make it possible for more people in the room to view it / expand your seating possibilities. I reference something like http://www.cdw.com/shop/products/Chief-Thinstall-TS318SU-Medium-Dual-Swing-Arm-Wall-Mount-18in-Extension/2555661.aspx?cm_mmc=ShoppingFeeds-_-GoogleBase-_-Video/Monitors/Cards/Projector-_-2555661_Chief%20Thinstall%20TS318SU%20Medium%20Dual%20Swing%20Arm%20Wall%20Mount%20-%2018%22%22%20Extension%20-%20_CIF-TS318SU You can even mount a television tlhat is wider than the wall behind as it can sit flat on the wall and extend beyond the wall to the left when at rest like another plane in your architectural composition. Since the upper stair is just behind, this should be fairly safe for the electronic. Determine precisely where the television will be at rest before you hang the mount itself. Then, look for a low height chest to sit below the television. Ideally a chest with one open shelf near the top to hold your component receivers. You may want to try to run electrical to the remaining vertical wall on the right (the support for the stair landing) to get power into the wall itself, while everything is open. Depending upon where the nearest source is, with concrete walls, you could mount the power junction box low on the wall under the stair and drill out small diameter cord passages through the wall after placement of your components. Or use the baseboard area to run needed cables and power to the area behind the chest, then conceal it with baseboard trim. The more you can hide the power and connection cords, the sleeker the look, to match your gorgeous architectural stair element. If you have a larger deeper television, put it on a sideboard chest under the upper stair where you have the depth. In the rear area, take care with putting cables together in a cord cover - ikea has a good one that is inexpensive. http://www.ikea.com/us/en/catalog/products/20097954/ so it looks "neat" from behind when you come down the stair.

I am planning to change my living room please suggest me for best type of sofa and celling. .my living room sign 9 ft width and 20 ft long ...please suggest design

Abhijith, Separation from kitchen can be done anytime during ceiling design and you can design separately to your bedroom too. But no design is the best design as design is always customized. So appreciate if you send your layout plan so that I can guide you by understanding your requirement. Regards
