Rowe Furniture has very clean line sofas that I think would be an appropriate scale for this room. LOVE the red feature wall. You do need to bring the red into the room but knowing how you want the room to feel can help determine a color palette. If you want the room to have energy and "pop", try a split-complementary or triadic color scheme. If you want it to be more relaxed and harmonious, I would suggest an analogous color scheme.

Hi Ni, I just thought of something....did you say you planned to do the stencil motifs on the window wall? If so, I am thinking they will be mostly hidden by the curtains. I wonder if it might be better to stencil the long wall that is on the right side of the room when looking toward the window. I could see this being a pretty backdrop to the prayer box (I think that’s what you called it?) and your wood cuttings. Then maybe the opposite wall (the one with the kitchen doorway) could hold a large piece of art?

Here are some photos that may help you. You have the ceiling height to have a nice heavy rod just above the top of you window that could run the ceiling width. That will give you the space to draw curtains back to expose the entire window. I highly suggest that you work with a designer. A good designer has access to literally thousands of fabric choices and will be able to help you in selecting the perfect fabric and design for your room.

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
