One possibility would be to swap the living room and the dining room. Since the current living room is larger than the current dining room you could still keep some comfortable seating (couch and upholstered chairs?) against the front wall for a keeping room/dining concept. Then your new dining areas (kitchen and dining room) and living areas (living and drawing room) would have good flow between them, which would work well both for family and entertaining. You could also add some builtin bookshelves in the drawing room or new living room to create a library area to add another fun element to the living areas. These bookshelves could be against the long walls in the drawing room, around the window with a window seat in the living room (former dining room), or built to create some separation in the open area between the drawing room and living room/stair area. Your plan seems to show some sort of builtin there, but I'm not sure what it is.

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.

OK... but the wire wont be lower as it is fixed now. The wire in the pics below is the wall facing each other. They were leveled on equal height but the beam on one wall makes it seem a little above. But i think you guys are absolutely right that up and down lights wont look good there. I think you are right about down lights lessismoore. Would it look good if i go with two different lights on opposite walls??? it would look odd right.

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.
