Hi, is the wallpaper shown as the solid color in the rendering?

Hello Monika, I must say that concrete wall is fantastic! I see a large planter with a large leaved plant there.. I like Jonathan's idea, off white or shades of cream for the remaining walls and ceiling or even a subtle stone colour.. Then we need to talk textures! I think the sofa could work if you move it out a bit from the wall and layer it up with throws and add a couple of lovely cushions.. Warm woods would be nice too to balance the room.. Have you considered adding concrete to other areas of the home? There are some fantastic concrete chairs available both as a chair and bar stool.. Could be fabulous to compliment this room.. Cox and Cox did some pendant lights that were concrete with a warm edge detail.. You could create your own arrangement with a 5 wire ceiling rose and hooks.. A glass topped coffee table could be nice too.. Have a look at eBay or vintage shops.. Oh and one more thing... You can if you like the concrete wall find wallpaper for another room say that resembles what you have in the living room or even marble! It's fabulous and a feature you want to make the most out of! :))

I think all white will be a very nice scheme and the differences in the white will just add subtle difference. In the above pic the walls are more white than the table, but mixing with the light tan colours and greyish tones makes this gradient of whitish tones work well.This room is all white as well with the furniture and walls, but adding the punch of the other colours masks if the whites are slightly different as the bright colours become the focus. The walls in the pic below 'read' a very pale grey so that would be an option, just ensure that it is a whitish-grey and not muddy or warm. I would choose the sofa colour as your main colour and accents to match from there.

I would suggest u to go with white sheer and light grey curtains only. If u want want to play with bright colours then it is safest if u add them in form of accessories or decors, reason one being the space is small n it’ll look more crowded then. It’s better if u avoid orange n yellow in this bedroom at least. If u can give a better picture of the accent wall colour here it would be better. Then u could go with a darker shade of it to form the colour scheme. White+Grey+Purplish brown. That’s it.
