Hi. Since you have such contemporary lines with the linear use of windows, I think your look is contemporary, but with so many windows, you still want a connection to the outdoors. My suggestion depends on whether you want to blend in with your surroundings, or make a statement. If you want to make a statement, I'd stay with a stark white, to contrast the sharp blue. Then use bluestone cut in a random pattern, to play off the blue roof, but keep an organic feel with the movement of the stone. If you want to blend in more with your area, then go with a mid-range gray color on the walls. It will tone down the contrast, and still stay contemporary. Not a dark charcoal, but not a dove gray. I attached a Gibraltar Gray from Lowes, or you might like a little lighter gray. Benjamin Moore has a bit softer gray: Cape May Cobblestone. Good luck! Please post your choices.

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 would prefer natural stone cladding instead of exposed brick decor. This is simply because natural stone cladding can provide a classy and elegant appeal to the home. Also, it is easy to maintain and lasts long. Another reason I would prefer stone cladding is that it provides a modern touch to the interiors. I would also prefer patterned tiles or textured walls over exposed brick as I feel that it makes a space look more lively and beautiful.

Hello Vipin, As the floor is dark green I would suggest a biege sofa, a very very light yellow colour for walls, light yellow and biege plain self designed alternately placed curtains, brighter yellow and dark green (as that of floor)alternating cushions and an orange base painting with white yellow and green on it on one wall.Hope my suggestion is of some help to you.
