Now it's beginning to work! Luv the rug! A few more red showstoppers, and I luv the post about matting your family pic, and larger frame for it. Looks like you might be a bit uncomfortable with the great post idea of moving your sofa out into the room away from wall. If so, could you accept putting it diagonally from the entrance doorway, across that corner where it is, stopping at the edge of your window? That's a bit of a move outward, still can see the fp and tv, and show off your new rug, which could go diagonally in front of the sofa. Then, if you like that, after a while you could move it on out as Deb K suggests. Sometimes intermediate steps are more doable for us than those big changes.Same with painting; if you could first paint just the fp wall, then later paint other walls...seems some color would really make it more homey. Would you cosider a quite contemporary fixture for the light in the center ceiling? Maybe a bit of red could go there!

As you probably know your current colour pallet is very restricted to the couch, curtain, arm chair, carpet and TV & TV cabinet. I would select a variety of colours from this pallet but use the tones that bring room into the living space e.g. I would find a huge, long pile rug that takes up the entire space between the couch and the TV, then add matching cushions to the couch and a throw for the arm chair. This colour of white (or cream - it is hard to tell in the picture) should really brighten up the room. The couch cushions and throw could also take on the black from the TV but my base colour would be the cream / white - what ever colour the curtains are. I would also add art work and a standing lamp. Maybe black and white art and a few nick nacks on the TV stand.

Hmm, I'd aim for balance. The last time these colours were in fashion, in the very early 1990s, I had light pink, light blue , light green and black. In some rooms there was white instead of black. They all worked well together. There are lots of recent pastel rooms on Houzz photos. Also florals are about to appear on the scene, in big digital murals and digital printing on cushions, on rugs, etc. it's a modern version, but still florals. Pink and the pastels work well with florals. Which way does the room face? If it faces South, in the Southern Hemisphere, go for a warmer colour.

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?
