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

I drew a very crude sketch, definitely not to scale, of how I see your room working. Essentially, you could treat it as two separate seating areas, which makes for easier and more intimate conversation when entertaining a lot of people. Trying to have everyone facing each other in a large room just won't work, and makes for very awkward conversation. I find that at parties and get-togethers, people go off in smaller groups of two to four, then mingle and move around the room to chat with different people. So, to that end, you could establish two conversation areas that will each seat six to eight people. You can also have some of your dining room chairs upholstered and comfortable enough to carry into the entertaining area to create extra seating here. In the far corner by the window, I placed a chair and ottoman, so that is seating for two, and before the get-together, you could place a couple of your dining room chairs over there to create a other small grouping for four. You should still have enough open area in this large space for some people to stand and move around, which a lot of people prefer to do at a party (I know I do!). The bright yellow sofa is a modern take on the old ?English sofa, which in think is the perfect foil to your ultra-modern sectional. The yellow is a bright, cheery - and unexpected - color, but works nicely with white and just says "fun" to me! The small blue tub chair(s) would be placed at an angle facing your white sectional, so you would establish a color,scheme of white, blue and yellow. To this, you could add black, Gray and darker blues through your accessories and artwork. The little blue ceramic drum stool adds a touch of the exotic (and more fun) and is easy to move around as a small side table to set drinks on.

@Genevieve : that kitchen was too small they had an island inside ,the client insisted for the kitchen to be interesting that is why I came up with an yellow The walls were already there it was a very small opening with a door ..Then it was made open type for better space

Seems weird not to incorporate it into the design -- I'm all about having things "look intentional" rather than working around them later. Like could the island have connected to this, rather than extending past it? or been L-shaped, so there's room for an extra stool, and also a wall cabinet? Anyway, hard to discuss that in the abstract without kitchen plans. I'm with miacometlady's original advice to not worry about it right now, and decide how to deal with it once the bulk of your kitchen is in place. You might find that you hardly notice it, with all the beautiful new finishes, or it might seem obvious to put some stainless or glass shelves there, or maybe simple is best and one simple hanging picture does the job. Don't stress about it until After. :)
