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.

am assuming this is a concrete structure, when shifting service toilet to utility area, and if there are apartments above, then running extra lengths of supply/drainage lines & introducing a structural sink slab (if this is concrete) under the new location can be charged extra.. it will be easier to divide the 3rd toilet. all services will be already available. only, do check on supply & drain pipes capacity as load is increased on the same pipes which were serving one toilet earlier..

go to a lighting show room, take pictures of the space and any ideas you have. They are best suited to help you. also have a budget. the how to part is nice but most consumers have no idea that the pendants above are probably 300.00 each. Budget for lighting! take advantage of the pro's in the lighting world, its all we do!

Your chandelier is a bit high, so all it is lighting is the ceiling. You could a light with a floor lamp in the corner for reading on the sofa, and a table lamp next to the bed. Other ways to add more subtle lighting would include an uplight or two to wash a wall. Start with lowering the chandelier a foot or so and adding the lamps. See if that doesn't help. Ignore anyone who says to remove the ceiling fans, because it looks as if you live in a warmer climate and you really need them.
