Hi preethaa, I don't think there is any rule regarding the the built-ins. I've seen some spaces where they've done some really amazing things with built ins, like photograph murals placed on simple flat front cabinet doors. I think it depends a lot on the space, the style etc. Probably the safest bet is to paint the built ins the same colour as your trim. It is a classic look and you will not tire of it.

Hi pankaj. Some lovely ideas above. Is that a door at the end of the passage? It strikes me, especially if you want to make the passage all white, that you might be able to give that door a special treatment to bring some drama to the end of the passage. That draws the attention to the door and away from the passage itself. You could just paint it a vivid colour. I think we tend to let our interior doors remain very plain and boring, when there is no good reason for that to be a rule. The one below would need some sort of backing for privacy, I guess, but I think to put metalwork on a door is a great idea that you could adapt in various ways. (Be aware of the dusting, though! Outside the rain will wash things clean, but not inside.) Also have a look at http://www.lushome.com/11-door-decorating-ideas-create-modern-interior-doors/58940 for some creative paint ideas -- I can't get those pictures to copy. I like the first one on that site. It's simple and geometric, and could very easily be adapted without hurting the budget.

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

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.
