If you want custom cream panelling built from scratch, it is likely to take you more than three weeks to line up a contractor, get it built and then painted. If you want to use beadboard (thin, lightweight, cheap) you can do it yourself if you are good at the small precision cuts around the wood window trim and behind the radiators. You can get a custom built wood cover with doors for your tv or use the painting over tv disguise made with hinges. I think the room is beautiful as it is. Spend some money on a truly beautiful, impressive chandelier, have it centered over the table. If you want to impress relatives at an event, the chandelier is the way to go. Clean the windows for extra sparkle. If you are in the US, try Home Decorators http://www.homedecorators.com for DVD storage cabinets that are closed. I would not get a rug for this room unless I was ready to get it cleaned frequently and I could find one that looked good with dog hair on it and did not show stains. A good quality, highly patterned wool Oriental rug will do that job nicely. Such a rug is an investment and may take longer than three weeks to find.

Gorgeous sofas! Would you consider using the Thibaut print suggested by Judy G Designs in a soft fold Roman shade? You don't say how many windows there are in the room. But Straight edge on the bottom, outside mount, clean and simple. The print has enough activity.

Sarsheen, you've created a lovely classic kind of luxury Edwardian effect. Fab. I think that's when those moorish tiles came into vogue initially. To continue on the theme - you could try one of those nice (wood or chrome) towel stands, which can be moved around. (Like they have in London gentleman-club type bedrooms and country-house hotels.). If you got a wood one, you could echo this with a wood framed mirror, perhaps ? A big fern type plant that loves the damp would look glorious too!

I'd try the inverse of what is suggested above- white on the panelling & dark grey on the walls
