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.

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.

Keya, glad you decided to take the one reader's idea about moving the armoires in front of windows that you don't need and giving the bed a wall of its own! And, yes, you can have Roman shades on one wall and layered drapes on the other. When I had drapes made for my tall sitting room windows/doors, I had them use the same fabric for the Roman shades for the smaller windows on the other wall. For me personally, in these older Indian homes with all the odd nooks and niches in the walls, perhaps it would be more soothing to have a light/med tone paint on the walls that blends with the drapes/blinds for an 'uninterrupted' look, and I would use the same color on ceiling and beams. (but that is just my thought) I would start the process with a large carpet with your favorite colors, then choose your Bedcover & cushions, then your wall paint and fabric for drapes/blinds ..Not certain what style you like, but if you really like a particular Ethnic bedcover fabric, you can always have them stitched into curtains or Roman shades too. Can't wait to see the "After" pics!

vedikaseth Bombay rains are harsh! The one thing you can do is use flexible covers that work similar to roller blinds, and are transparent which allows the light to enter. There are many companies that offer such a product. Just choose one where the installation is easy and taking down the sheets is not an issue once the rains are over. Do keep in mind however that the water will still enter the balcony, you will simply be reducing the force of rains, and will require a water outlet.
