Hello Bharati,
I will help you in decoration of your living room you should firstly choose a colour for living room I will give you suggestions of using white and grey combinations of colours. Remove all the junk from the living room.
Paint walls:- You can choose any colour white or grey.
Sofa:- As In instead of sofa I would like to suggest you day bed it will work as sofa,double bed and also has three drawers,don't need to use single sofa it will also save space.
TV cabinet :- There are 2 cabinets use closed cabinets without glass to keep things like chargers, books, etc.
curtains:- Use grey curtains of your choice.
Flooring :- Use wooden flooring wallpaper.

Hi,
You can consider planning out your living room with a compact sofa and a wall fitted tv unit for better open space

hi Bharathi
i suggest (sorry i am late to reply) ..you need to invest 3 units of furnitures with compact storage. too many small furnitures might cramp up thr place. Light shade if paint will make it look very spacy..
you can check out what i have..one of ur walls can be a darkshade..(the side facing sun) . most importantly.categorize ur items like what u use day to day/ weekly/ yearly. without planning on the grouping of items which u need access too do not pick the furniture. later you will find the storage are not much helpful. As the space is compact a little planning ahead will help
