Like your space and choice of green. Like the green in the kitchen you referred us to. Looks a little darker or less yellow than one you did with Photoshop? You have the same issue as many of us, for one reason or another we end up trying to blend two disparate styles. The couches say man's room, formal, brown wood to me. Your room, kitchen and fireplace say much lighter in colors , style and spirit! If you try to blend the two you will end up with neither. Your purchases to go with the couches will just add to things pushing you in a direction you don't appear to want to go! I'd suggest you find some sofa covers, or even bed coverlets if you can't get covers to put over the couches. I like the colors in the fireplace. Please tell us more about what styles you like.

My daughter painted all walls in her two bedroom house one color. It makes a small house look so much bigger. Take a look at the BM OC colors. There are so many wonderful off whites. One of my favorites is Collingwood.

I quite like the colour scheme, it's looking good!

I think, like you said, due to the fact that there's a larger space when it comes to the hotel lobbies is the reason as to why it works. I think that no matter what you put on the walls (whether it be concrete or marble) will result in tiles not working out. The industrial look tends to be exposed brickwork anyway, or cream or white colours so maybe that's an option you could look into. What did you end up doing?
