Thank you roj leather and Simon for your recommendations. I like the hanging chair and the almanda creeper on the wall. This will certainly liven up the patio.

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

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

Just because you want to use the space below the stairs, do not just add drawers or shelfs unless you reaalllyyy need it. I would suggest go for adding something green to your house. Its healthy by adding air purifying plants. These plants are nowadays available in most of the nurseries and moreover Green patch in the house gives a beautiful look to the house and is also good for eyes ( the green color). Below are few picture to motivate you for Green patch or Indoor garden.
