Priyanka, Wallpaper on doors is not a good idea. You can go for laminate panelling on the wall and matching laminates on the doors. You can choose a veneer as well. The space is too wide for a single door though. You will have to plan accordingly. I am assuming you are talking about the brown door and not the other black door in picture.

Hi Is your accent wall is right or left to staircase? Going with urban bronze to the left of staircase is suggestable ( since it have enough windows to provide lighting) Going with urban bronze on right of staircase is not advisable.Since i dont get that wall will get enough lighting.. Making a contrast with bronze shade is a good option but I suggest you dont go with .Because as per your kitchen shape , cabinet and tile material ,Just leaving everything with neutral colour would be preferable than going with bronze shade Thank you

Veneer with White PU is a great Option. Alternatively you can go with Duco which is slightly cheaper than PU. Laminates always have a sharp edge unless done with the right expertise. Fabrics, if going with white, should be scotch-guarded. Mostly, white PU will work on table tops too, but if you want to use a sturdy option, go for white lacquered glass or White marble.

Go for white shades which has hint of green (example Absolute white L161 Asian paints) as there are lot of dark colored elements here and needs to be balanced out and is also good as per vastu. I really like thw furniture and small wall decor you have here.. but I really feel it is underutilized. A good interior designer can really turned around this room with very less expenses and modifications. Please message for any further queries and let me know if my suggestion helped you.  Regards ὠ0
