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 cant tear down the wall. how to camouflage the wall? i was thinking of creating book shelves with low sitting arrangement.

Ka_kamakshy interior architect , Did you check with your contractor why he thinks it will fall down. May be he hasn't done it earlier or he doesnt want to do it. It is very much feasible to clad the walls with marble/granite/ other finishes.
