It's a rental so buy something that you can take with you that will work in your next home. Just stay with green and white. You may not be able to change the panels, but you could add to them where it can't be seen from the outside. Add white to the outer side of the blue panels. Then get a navy and white throw pillow for the accent on the white sofa.

If this photo from your ideabook is the look you are going for, try adding a rug and inexpensive coffee table. To keep budget down, try an indoor outdoor rug you may find on sale at the end of the summer. The other thing you could change easily would be curtains or other window treatments in a zingy color or pattern. Perhaps there are curtains in another part of the house that could be swapped with these? Try taking them down to get a good look at the blank space possibilities.

I've been looking at these plans for about half a hour now and I'm stumped. What did you guys decide on doing? If things came down to it, you could remove the fireplace. But I'm guessing you don't want to do that. Let me know what you decided to do!

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?
