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!

Have you ever thought about floating shelves? I think pairing a few floating shelves together would look great and would free up space in your living room. I really like the Eugene floating shelf from Bryght and I think it would compliment your existing pieces. http://www.bryght.com/product/160/eugene-cocoa-shelf

hi chk I tried completing your living room . I guess the asymmetrical look of the living room needs to be combined together with some symmetry . 1. So you should get a big rug or 2 same rugs and curtain in same color lemon green or any other color of your choice . 2. you need to get 3 more peices of that lantern. one of same ht.used and 2 of a lil small ht. 3. you should get 2 lamps for the other side. they should be not small in ht. your one side have mirror so your window treatments and lamps will be reflected in mirror . 4. if you want to keep those table decor then keep it in centre and donot scatter it . also you don't have to keep all candles try to make a tray wid one or 2 candle and kettle's tc on main coffee table . for the other side a crystal vase with some green planters and flowers on 1 table wil look good.

I would suggest you to go for either actual stone cladding or ceramic wall tiles. Natural stone cladding provides a rich look to your walls and last comparatively longer than wallpaper. Although initial cost might appear to high but in the long run, it is the cost-effective solution for your walls as it requires very low-maintenance. Going for wallpaper would not be a very nice option especially if you are looking for something long-lasting. They not only get damaged easily because of moisture or other factors but would also stain your wall when they come out. Ceramic tiles is also a nice option to go for. You can get a huge variety in terms of size, colour, pattern etc. If you are looking for not-so-expensive option then ceramic mosaic tiles is the viable option. However, you should know that ceramic tiles take quite a long time to warm up during winters and cool down during summers. Wooden Planks would make your interior look elegant but it is very susceptible to temperature change and can easily get damaged with water. Also it might not go too well with modern architecture. Hope this helps. Thanks & Regards Kapil Surana
