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.

Namrata, If your intention is to let the light in and yet maintain the privacy then vertical blinds would be one of the good functional solutions. See the attached image for your reference. Note in your pic at this angle it looks like the TV unit ledges have been taken to the far end of the window wall. This shall pose issues with your curtains/blinds as well. We mean to say your curtains will not close on the right hand side completely.\ Hope that this is not right. Let us know if it is. Thanks Nitin Cornerstone Designs, Bangalore.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

Just because you want to use the space below the stairs, do not just add drawers or shelfs unless you reaalllyyy need it. I would suggest go for adding something green to your house. Its healthy by adding air purifying plants. These plants are nowadays available in most of the nurseries and moreover Green patch in the house gives a beautiful look to the house and is also good for eyes ( the green color). Below are few picture to motivate you for Green patch or Indoor garden.
