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.

Pankaj, I just realized that initially you told us that the bathroom area was 12'-0" x 9'-0" and later you mentioned that it was 11'-8" x 8'-0". In the last floor plan, I forgot to change the bathroom with the new dimensions. Below is the floor plan with the correct dimensions for the bathroom. The bedroom is ok, I drew it 19'-2" x 12'-6". The new layout does not change the way things are placed. Everything still fit. The only difference is that the vanity is now 4'-4" long instead of 4'-8". and the toilet is closer to the shower by 1'-0". Can you give me the lengths of the walls K and L. They are the walls between the vanity and the shower area. I will send you the new layout once you give me the length of these 2 walls.

16' long is a lot of room. Can you post a pic of the rest of the room? Remove every door you can. Every doorway does not need one and doing this one simple thing will remove a ton of bulk and make your space feel more open - no need to remove the hardware if you think you might want the doors back sometime in the future. Are you up for painting the walls and possibly the trim? Is this a sectional? If so, you might have to split it in order to get it to fit. The curtain into the bedroom is a good thing. I have used that idea, I love it, and I am not from India! Change them out for a lighter color and add panels to the ones you have - make them at least 3x fuller than the doorway. Pull them all over to the hinge side of the frame after the door has been removed. Your pictures need to be rehung and you can address that once you have found a furniture arrangement that works.

the board is installed the wrong way to start with. it should be horizontal to achieve the rustic look. why do you need a painter for such a small job? try to remove the existing finish with mineral spirits or a heat gun. apply a coat of white acrylic primer and sand with 300 grit paper once dry. clean with vacuum. apply a coat of dark grey emulsion. dry. then spray a coat of white automotive laquer very lightly. usually thus dries quick in 30 minutes. very carefully sand with 400 grit on the grains and you will now have the desired finish. cost of materials approx 1000rs.
