You do not mention whether you wooden wall will be painted or stained wood. Either way, there paint products you can use to properly seal and protect the wood either way. You should visit your local paint store and tell them what you are trying to do and see what products they recommend.

I have some suggestions if you are thinking budget friendly changes. Make a photo gallery with different size frames and arrange them parallel to the stairs, so you can enjoy each photo as you climb up. And for the area that will be on a level with your upper floor, try some pretty decal that will connect the photo gallery to upper level. And last, if you have budget add some beautiful hanging lights in the stairwell. Also think about repositioning your refrigerator.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

Yep, I agree it's nowhere near Scandinavian. Although I tried hard to emulate it with the resources I had and conflicts with other family members, but oh well. But I'm trying to emulate the Scandinavian theme at least in the paint job. Do you think if I somehow achieved it at least in paint job it won't look good? I really like the color scheme of Scandinavian design. Edit: I really like the minimalism and coziness scandinavian design provies. Although, I do have to mention that I didn't mean to say that the photos that I've posted are necessarily scandinavian. I was just talking about the colors especially the white color.
