You want to hide wiring? Is it in conduit or armored cable? Exposed wiring is illegal in the US...sounds like you are in another country? So if getting the wires behind the wall can't happen, putting it in extruded metal tubing (EMT or conduit) is a safer option. Then embrace the necessity and go for a hi-tech/industrial look. Reclaimed and re-imagined furnishings and parts from factories and workshops to play up the look. Search "industrial" under the "browse rooms" tab in the Houzz header. Regarding hiding switches...hiding them is not so great...you kind of want them accessible when stumbling about in the dark! The EMT electrical system has metal boxes for mounting switches, outlets and light fixtures. And metal cover plates too.

Love the armless sofa-bench! Try using it in the center as a "cross-linking" piece between the sofa and chairs. That way people can sit on both sides of it, conversing with the sofa people and the chair people. Put the chairs where it is and use the side table from the left of the pic, or the one with flowers, between them. You'll need one huge rug to anchor the space or two smaller, and very similar ones, to put on either side of the blue sofa-bench. The other two side tables are too tall and too short for your seating pieces, so ditch them. Use your coffee table between the sofa and armless sofa (18" away from each of them.) Here's a chart for judging table and lamp heights as you'll need to work on that for balance. Please try this arrangement, and post by commenting and using the Attach Images button to add pix of the update. We'll tweak it on out from there.

HI RinaI do agree I love jewelbox rooms, but I consider them more cosy ... and with a grey marble floor it goes all Versace Italianate! I am trying to balance the colours by bringing in a pattern on the covers rather than plain. I feel this will bring colour without overpowering the room. In the pictures I showed above, the rooms are basically neutral but the colour is brought in via pattern - I think this might be the way to go...Ideally a green or blue on a subdued grey would be the best, but I dont know what the market is like for Sumit...Cushions can do a lot to tie in the other white/grey elements.Shelley - navy is a good suggestion, but as Sumits area is quite tall and thin, trying to keep the general area light Any more suggestions most welcome. These are just ideas after all and Sumit will choose what works for the room in the end ;-)

First of all, I don't think that furniture is comfortable enough to sit and watch TV, so the TV should be remove from that room, the purple wall paper and the purple furniture is too much, you should consider another color for that wall and the furniture against the wall it doesn't look good. What is that room at the end is kind of dark and I cannot appreciate exactly what is the purpose of that room. I'm a firm believer in skylights, we have skylights in the laundry room, kitchen, living room and office, they make a big difference. (if you cannot have skylights (or tube lights) can lights are a great option. There are a lot of great ideas from everyone. I can't wait to see the after photos.
