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.

Vikrant, is the picture taken from the front of your Entry door? I love your style and pieces. Just a few suggestions if this is the view when you first step into the foyer, I am not an expert! Ganesh in the place of the mirror to greet you and your guests as Goddess Lakshmi is supposedly behind him, will create more prosperity to the household. A recessed focal light from the ceiling to highlight its beauty. Another silver empty frame placing behind Ganesh, similar to the mirror to frame the idol or a Rajasthani silver jali work piece that way the wall behind would not look empty either! The beautiful mirror can be placed where you have the Ganesh now, that way the positive energy coming into your house does not get bounced back or out...

hi Abhinav, I have a few suggestions. I'm guessing there's a window in the living room. this can be converted into a u-shaped seating space as shown in the sketch along with 2 upholstered accent chairs which will help in achieving a classy look. you can add open or covered storage below the seating. A 4 seater dining table as shown in the rough plan cad sketch can help you achieve both a living and drawing space in the same area. Also, the passage has a wonderful nook that can be used in many different ways. place a winged armchair with an overhead lamp and floating bookshelves along with a simple wallpaper. Or you can also add an 18" wide wall attached counter there with stools, add some funky wallpaper with vintage posters and turn it into a diner! this space can also be converted into a mini Bar! hope this was helpful. cheers!

@Cornerstone design studio: Apologies for making big post; thought that more info will help. @Rupal ji, If it sounds like I dont need any changes; my apologies for that. Let me put it in short,"I am looking for options that give modern facilities without leaving good things from old charm/ comforts. " Thanks for the straight forward comments. I shall try to edit my original post to make it simpler and that looks open to new ideas.
