Would need to see the elevation.

Rohanth, See if this inspires you.. alongwith some of the ideas suggested by RMs above. If its feasible please do away with the grills and replace them with tempered glass. You may have to play with lighting to enhance this area. You can call us ..its easier to explain over a call . Thanks Nitin CORNERSTONE DESIGNS Bangalore.

two basic issues your room floor is dull is that floor to floor carpet if yes then add a a smaller area rug under your table to get splash of colour, alternatively if you dont want to do that then add some colorful wallpaper behind the sofa. Where you have the table lamp add something taller like a modern floor lamp or a tall spread out palm plant. Take the table lamp and add to a side table if you have one. The second biggest issue is that you have a lovely modern sectional sofa and then you have paired it with a very traditional and very high coffee table that looks like it has marble inlay work done (cant make out clearly). This is not a good pairing. The coffee table is the right size but get something modern and a lot lower, a general guide to this would be one inch to 2 inches lower than the seating height of the sofa. As someone else mentioned an Ottoman that can serve as a coffee table in an alternate colour will also work. Paintings and wall art is something you can experiment with but unless you do something about the coffee table the room will continue to look odd in my opinion. Also some more shots of the room will help us get perspective.

As it's a North facing house, I would suggest keeping most of the openings to the north, will illuminate your house beautifully and will lessen your electricity bill. A duplex will be suitable according to the area and requirement. That will allow keeping a lot of open space which will give the feeling of being in even larger space than it really is. I hope it helps. I could have suggested more if I knew more about the project.
