Just a little ceramic information to share as a potter. Vitrified simply means the clay has become glass like by being fired to its proper maturing temperature. Usually ceramic tile means it is a lower temperature clay like earthenware or terra cotta. Porcelain is fired to the highest temperature and is more vitrified if you will. This usually means it is less porous to to absorb water and harder. Low fired ceramics with glazes much darker or lighter than the clay body will show chips easier. Rectified has to do with making the edges precise enough to fit smoothly together for less grout lines. So porcelain cost more to produce but it is more sturdy. All clay tiles should be vitrified.

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?

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

I would take away those top arches and have builtins either side of fireplace, have the tv placed on a shelf on the built in, like in the pics, you don't have to have it above the fireplace, if room is small it will feel like it's coming at you lol. Panel above fireplace and hang some artwork or a nice mirror. Quiet like the builtins with the back wall painted
