You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

In my opinion, a cuckoo clock is a very detailed design, but you say you want a simple design for the room. When you say simple, are you thinking of no wallpaper, no wainscoting, and no accent color on the walls? It seems as if dark orange is a color you favor. I see it in art images and in your curtain color. If this was my space, I would paint all the walls one or two shades lighter than the beige of the sofa to keep the room as bright as possible because the room has no direct sunlight. I would paint the ceiling 1/4 (one part wall color to three parts white). I would use a satin or eggshell paint instead of matte, semi-gloss, or high-gloss paint. I see some discoloration on the wall behind the sofa where the brown color of the sofa frame has worn off onto the wall. I suggest attaching bumper dots or strips on the wood frame of the sofa (similar to the ones used to keep cabinet doors from making a lot noise when they are closed quickly). I would consider painting the sides of the column with the cuckoo clock brown to match the clock. I would do this to call attention to the clock. I would remove the orange curtains and replace them with floor-to-ceiling length draperies hung as close to the ceiling as possible to make the room seem larger and taller. I would change the drapery color to match the walls, perhaps in a muslin-like fabric, which is a casual fabric. I always take my art to a professional framer. I have conservation matting and museum glass used for my art. I would have the three images you have rearranged as a collage in a very large single frame with medium to wide matting between the images. I would have the mat and frame color(s) enhance the images, even if it is a color I might never have thought of on my own. I would hang it above the sofa. I would use the orange drapery fabric to make throw pillows for the sofas. You did not attach a photo of the flooring in the room. A medium tone floor is easier to keep looking clean than a light floor/rug or a very dark floor/rug. Other "Houzzers" will give you completely different ideas. Use the ideas YOU like and enjoy your home!

I think I am certainly quite late to reply on this post but nevertheless will put my suggestions here. Go for 2 loveseats in a light/neutral colour against the 7 ft and 15 ft wall. Opposite the 15 ft wall you could put a nice upholstered bench in contrast/printed fabric. Also for a warm glow put a nice standing lamp in the corner between both sofas. You can place a nice mirror on the TV wall and put a nice shelf beneath it and place a lamp there with few knick knacks if the door opens outside in the balcony or is sliding. Also, keep two upholstered ottomans below the mirror which can be pulled for extra seating when required. Place a low height coffee table small one like a 2x2 ft.

Hi Manas, There is one option i.e. if you don't want to do any major changes you will have to take the wiring from sofa wall till TV wall and you can hide it using conduit. Or You can take a grove from one wall till the partition wall and get it filled. Partition is supposed to be a ply wall of 3 inches which will have framework in center and ply on either sides. We are attaching two reference images one with designer panel and one with plane. You can use whichever you like. We hope this will help you achieve your required design. In case of doubt, queries are most welcome. Best Regards Team Offroad
