OSB board will do the trick. You need another photo for us to offer a species and finish. Natural finish (clear coat...water based polyurethane finish...NO oil modified) in a low gloss or satin finish on white oak with FLOOD LIGHTS will offer the same "look" as the poor photo. Beyond that, you will need a better photo.

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.

Thanks. Somehow I did not have luck finding good carpenters, Here is how I wanted the drawers to look. Here is how carpenter from my locality (not too cheap a neighborhood, called Lokhandwala) tried to make, A you can see, he tried to chisel the wood to get this design. Obviously had no clue. Finally he gave up, Brought the unfinished desk in with an excuse to show me how it is coming along, left it with me and never showed his face again. So I tried an expensive carpenter, who did some work at an apartment on NapeanSea Road, a very expensive locality and paid him what he wanted. He too did not know how to make this. All he did was out a moulding in the center to make it look .as though it were similar to what I wanted. At least his work was clean, except that he represented that the top was teakwood while I lter found out that it is mango wood, but he too did not know how to get this done. I hope one of you can suggest a carpenter with some skill.

Its just really messy right now. Too many colours and clashing prints. Is that Puja unit lime green? Or does it just appear that way because of lighting? Either way, it stands out like one more distraction. Pick one base colour add and add prints that go with that base. That TV unit HAS to go. So do that black metal coffee table and the carpet. I would suggest you go with a simple geometric print in the carpet. But apart from these obvious design gaffes, the structure has distinct possibilities, if you do a classic English style. The railing above adds some interest
