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.

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

I would suggest using a blackout and thermally insulating roller blind, and sheer drapes inside that. You would be able to use the sheer drapes most of the time, and the blinds for hot sunny weather or TV when the sun is in the wrong place.

Hi Nishi, Beautiful furniture and a very cute cosy nest you have. To begin with replace your existing coffee table with a hard wood simple coffee table. Replace your cushions with an assortment of pink, turquoise and golden yellow in different sizes and shapes, this will add some brightness to the room.Replace the pictures on the wall with a big mirror as per the wall size and add a nice frame to it. On the shelf on the picture wall place the candle stands currently on the centre table. The stools can be replaced with a nice upholstered ottoman bench in a printed fabric as sofa is plain. Cover the entry door with curtains as well so that it gives an illusion of a single wall behind. Since the wall behind the bench is already textured do not put anything on the wall. Remove the white bench there, instead put two big white teracotta pots there of different height and put bamboos on it. Finally put a blue/brown shaggy rug below the coffee table to complete the look. Hope you find the suggestions useful. Also you could put a few glass shelfs on the wall behind the 3 seater and place all your small knick knacks on displayLike how I have done on my wall
