Mustafa, my apologies for the delayed response! I've been thinking about your dilemma and this is what I've come up with. I'd make the most of the vertical space in the room so that you allow yourself maximum square footage for counter work space. If you're able to, I would suggest putting the refrigerator on the opposite wall (where the tall storage unit is in the sketch). Something similar to this:

I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have. The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work. I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall. If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos. Here's an example, you note this picture would be a lot more stark with an empty table: https://www.houzz.com/photos/21-house-contemporary-living-room-san-francisco-phvw-vp~60642

HI RinaI do agree I love jewelbox rooms, but I consider them more cosy ... and with a grey marble floor it goes all Versace Italianate! I am trying to balance the colours by bringing in a pattern on the covers rather than plain. I feel this will bring colour without overpowering the room. In the pictures I showed above, the rooms are basically neutral but the colour is brought in via pattern - I think this might be the way to go...Ideally a green or blue on a subdued grey would be the best, but I dont know what the market is like for Sumit...Cushions can do a lot to tie in the other white/grey elements.Shelley - navy is a good suggestion, but as Sumits area is quite tall and thin, trying to keep the general area light Any more suggestions most welcome. These are just ideas after all and Sumit will choose what works for the room in the end ;-)

Dear Amit, Thanks for working on the same and pointing out the things some of which I have not thought of.I am attaching the main design which was given to me by the builder.I She have worked in the main plan and made some changes as below: -She have clubbed common Bath as per the original plan with the MB to make it bigger,but no option was seen to extend the attach Bath. -I was thinking of keeping fridge at the kitchen and W.M inside the common Bath. -She have suggested sliding door in MB which I can change it. -I haven't thought regarding the position of the TV .You are correct that it will be too far. Can you please suggest how can I utilise the spaces in a better way. -The work which have been done is as below: 1)We have broken the common Bath wall and clubbed it with MB. 2)One wall of the kitchen have been broken to make it a open kitchen. 3)She have changed the location of the main entrance from 4th part of the south ,as I didn't have any option to change the location of the main entrance to other direction .As per her 4th part on the south from right is ok for entrance. 4)Right now the entrance is as per the builder design .We haven't changed it till now.
