I think it would depend on the color you are going to use for the curtains and bedding. I think something very neutral on the walls such as a light brownish taupe would give you the most flexibility. I would take the wallpaper into a few paint stores and get some ideas from the people who work there. They can be very helpful.

Instead of the solid grey, you can go for sketches in grey with flashes of mustard/ yellow. Or, look up these links for wallpaper ideas https://goo.gl/images/OrCtY1 https://goo.gl/images/0ZpAmU

I know all the houses in side would be beautiful, but went with the last one as the tiles outside give me enough info to have an idea of how beautiful ( if not beautiful) at least layout wise and material wise, how it would be, Now, can we see the inside please? hehe*

Hello Harsha as you are going for brown color for wall cladding and the console is also in brown shade, so in order to cut the monotony of same color you can go for an ivory countertop to match the grain shade of the brown italian. Also if u can use anything part marble you can go for a nice corian shade. For any further assistance you can drop me a message would be happy to assist you. Regards Tamanna Pawar
