we were thinking of having white bar .. by having a nice white wallpaper with a white cabinet which will have niche containing pictures . with each niche having a light . the picture sent for the bar table will have light effect as soon in the earlier picture . please do let me know on how you feel about it ?

Actually, there is a designer who has designed a sofa/table piece. You can see it here - http://kononenkoid.com/julia-kononenko-projects/convertible-sofa. That may help you visualize your planned project.

Yes, JudyG that's exactly the way people were using the taller table. Sort of a café look, or casual bar setting. One home had a beautiful huge kitchen all done in white with dark wood floors and RH style fixtures and hardware. Where you would normally think would be a traditional dining room, they had made it up with a large high table and 6 barstools. It almost looked like an extension of the island. Another one was in a very open and light kitchen. It was smaller and where you might think of putting a breakfast nook they had a round café-style table with four barstools. I liked it because it gave a more casual appearance. If people were sitting at them, they were on the same level as those working in the kitchen. Almost like a bar at the island for that effect, but with some separation.

A McSo. Couldn't the base of 15cm overhang be supported end to end with steel. As a single steel structure mounted on the larger cabinet area visible here. It should be sufficient for supporting the extension. Corbels will provide additional support but IMHO may not be required. Have you thought about an semi circular or a D shape counter to avoid sharp edges. Thanks, Nitin Cornerstone Designs, Bangalore.
