I would use whichever Asian piece fits the tv as a tv console. Then purchas or have custom built...two large column bookcases one on each side of the credenza...to reach to the soffit. Install glass shelves in the bookcases. Get rid of the cream sofa...I can't tell what is opposite it, but, it is white. It looks like you have too much large furniture all fighting to have their style be "the winner" and nothing meshes. Use the lower asian cabinet under the window...then a cluster of the traditional style chairs grouped for conversation. 2 and 2 facing each other perpendicular to the window. The small tables could be between the chairs. They could be very similar to the armchair that is in the picture, not matching...but the wood frames all the same color and the upholstery the same. Then repeat the upholstery in decorative pillows on the sofa. Using the armchairs in the traditional area, gives you lots of flexibility as you can easily move them over facing the sofa when you wish to create a larger conversational grouping, or facing the tv when there is something special you want to watch. Get rid of the curio cabinet and the round glass table as they are too much in contrast with the leather sofa. Paint the smaller tables in a bright color to add a pop of color...repeating the color in pillows on the sofa. (I see an orangey colored throw on the sofa...that would be a nice accent color) You could add lights in the bookcase columns for interest. Then, look for an unusual lamp or chandelier to hang in the corner behind the curve of the sofa. I would hang floor to ceiling draperies with the large grommets in the top to repeat the medalian on the asian pieces. Add a wide band of the accent color to the bottom of the draperies. Place 2 unique wall sconces on each side of the wall unit...something that draws the 2 styles together, maybe with hints of the accent color. A large piece of artwork, which includesvthe accent color, to be hung over the sofa. It would be fun to have a frame in an ornate traditional style, but painted to match the asian pieces. Thanks for the opportunity it was fun!

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

I think this piece is quite lovely. It appears that your couch and chairs have dark wood so I would be tempted to stain or paint the buffet to match these items. Changing the large modern handles to smaller antique ones might help to make it less bulky looking and tie in with the other items in your room.. I like the idea of putting a mirror in the upper door, however much as I like the criss cross effect in the sample pictures, adding more detail may conflict with the curves in your sofa and chairs. You could look for a decorative detail that has more subtle style. As for placement, it might go on the short wall where you have a bench or even on the wall where you have your table with two chairs, one on each side to balance the look.

Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.
