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:

Thanks for ur advice guys ! Is there any other color advice ? Like brown n beige mix . Will it suit the high walls . I seriously don't have any idea as how to use the color . I tried a green on the walls in Photoshop . It looks totally lame but just want to know how to mix the colors . Any suggestion on how and where to use the color will be appreciated . Like dark color on the wall which has the TV and light color on all the other walls or opposite walls with the same color .. Pulling my hair out !!! I wanted to go for the black sofas only cos of low maintainence . It wil not get dirty soon . The one big thing under the staircase is my fish tank . The one near the wall is the TV . Yes we have fans attached on the walls . Since we have a high roof , we cant use ceiling fans . And the house is not equipped with a centralized AC . I just want a color which will helps me relax and will also look modern .

Thank you Groveraxle for the virtual ! you are too good a designer that is why I cannot help troubling you ;) you have your biggest fan in me ever since your first advice:)) As for an in-house designer I am certainly going to call somebody soon . Just that I get such a lot of options and great advice from highly accomplished and talented Houzz designers ..I would be better prepared after these conversations ..please forgive me for pestering you guys like this:)
