if we make little modifications, Have a circular seating arrangement on windows side, U have working table on the front, because u have big store on right. we can turn arrount the center table, i feet that may be the best

A houzz contributor, not too long ago, had made a wine rack out of 4'x4' wooden pallets, that are used in the US to move a load of goods with a fork-lift truck. Perhaps they have them in your country. He cut them in half so they were only two feet deep and stacked them up to high counter height. The wood would be a nice contrast with your concrete, might add a little warmth to the space. cascio.offsite@gmail.com

Buy a credenza for the TV so you don't end up with chronic head and neck pain from having your head tilted back in an unnatural angle. Find a nice picture or other piec of art work that reflects your personality to go over the mantle. Take some more pictures of the room so we can see it from more angle, and can offer you more help.

Please add a little more info...do you plan to buy more furniture, area rugs, lamps, etc? Can you provide additional photos from different angles and dimensions? All this will help posters to suggest things that will be helpful to you. I think you wneed one or two area rugs depend on what you want to do with the area behind the tv watching area.
