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.

Thanks Dytecture, help needed with seating guests who are to be entertained in the bar ...can I keep something infront which can face both screen wards and sofa wards as and when required? Any picture to suggest?

I would then suggest a medium gray. You may wish to change your curtains and bedding to black or dark grey (as you can use them as black out curtains. I would also add a large black carpet that will help absorb echoes from the room with your sound system.You may wish to center the bed underneath the window

Anita Vitrified tiles by themselves do not particularly allow the walls to breathe, and hence are prone to cracking. That being said they do not collect moss either. If you are however set on using these tiles, I suggest you use them in a mosaic fashion, where smaller tiles or broken pieces are used. This will allow the wall to breathe, though the moss collection might be more due to the greater amount of grating.
