I like the concrete bloc walls. They are becoming quite fashionable today. I'd keep them in the natural concrete color or if they have been painted, a color paint that resembles concrete. The concrete walls give a hard and cold impression so I'd choose wood flooring for the floors. The combination of a warm wood on the floor and hard, cold concrete on the walls is a nice one. Brighten the space with colorful modern art.

jacquipru: I kind of like it without the lamp. Do you need the lamp there for ambient lighting? If so, then the blue/silver shade for sure. My family would love for me to give advice on other matters. Keeps me out of their hair. HA When you start the other discussion, be sure to include lots of pictures, and include information like "I need to work with all the furniture, except for _________." And what kind of budget you are on. (Champagne vs beer!) You'll get TONS of ideas, but if you aren't working (sorry you are sick) and need cost-effective ideas and products, leaving it open ended might not be as on point and helpful as it could be. It's also helpful to generally indicate your location if you are comfortable. That helps people develop ideas based on what stores/vendors may be available to you. :)

I am planning to add scatter cushions and think if I do a pair of larger ones for each end so they go over the arms to creat height at each end, and a couple of smaller ones, I want to bring some colour in too. I do like the idea of a larger side light at either end to, Switching the sofas is going to be my final fix if all else fails!!

My very first thought was to paint the ceiling white. Some colourful artwork would be nice I think. I see you have some blue cushions, so some art with that colour would be helpful to tie it together and also a rug on the floor. What about a lampshade with a shiny chrome stand A tallish plant or two in white or pale coloured pots placed somewhere on the TV wall. I see something else on the back of the lounge suite that looks an interesting colour. Wouldn't hurt to bring that colour into the room too.
