Thank u all so much, though I must clear the confusion on the pic I posted... The actual space as of now has -'no cladding or wood planks' what so ever, it does have the same rectangular shape, the same ceiling pop, with the same electrical points for TV, and a balocny at the opposite end. Which is why, I was seeking your feedbacks. :)

Well it depends on your wall color as well . since you have such concrete looking floor I would recommend you can chose any electic color like lemon , orange , yellow to give a bright look and uplift room mood or chose any pastle color of your choice for subtle feel . :)

You need to mention your budget for us to advise a suitable method of which there are countless. Whatever may be the method we try, in retrospect it would only be secondary to real concrete and therefore would lack the solid raw monilithic almost indestructible character. The second reference image looks like a tile. The first image is a textured wall which can be achieved in several methods and quite obviously the price will go north the more you try to get closer to the real thing i.e raw concrete. Look up Dulux concrete effect as an easy method. In any case in our country the easiest method would be to use fibre cement boards and engage a wall texturing specialist to create the concrete texture as in the first ref image.

It would be better if you can consult Admixtures company like ., Myk laticrete, Bostik ., etc It's a kind of plaster STUCCO...
