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!

Your room is big and void of color. Yes there is too much brown. If not replacing. Add light colored pillows big in a cream print. Add teal to mix. Get a 8 x10 area rug. Go cream base and a contemporary design in very bold colors, red, yellow and black, teals mix it up. Can you get regular chairs. Those look like game chairs, can they go in kids room? Pull sectional into room out of corner face TV wall. With big rug and a 36" ottoman square. In a color. Maybe zebra for fun. On TV wall. Get a wall to wall floor to ceiling or close to it wall unit. Ikea has some go white. Get. Long low media cabinet. Also Ikea in white. Place TV on top. Fill wall unit with colorful pots candles books. Just don't over do leave 50% empty. You could paint that wall a darker (2) shade of walls. After you have centered sofa in room more. On wall behind a very large art contemporary 40x40 hang very low. On empty wall in dining area. Get a long 6-7 ft chest. Something different. Asian feel red lacquered would be fun. Over it add big art piece bold colors 40 x40 hang 6" above top of cabinet. More art big by dining table. I would change chairs to a high back leather in Teal. Pier one has them. Your whole place needs color. Area rug under table 8 x10. Solid teal. Add big palms in corner to fill and warm up space. In chairs get two swivel barrel type in a print. Modern go taupe and blue/greens. Wi Dow panels on ends only in teal. Ck bed n bath. TJMax a good source. For art ect.

There are so many wall colours that would work with your neutral furniture, that the first thing to do would be to consider what colours you might want to use in the rooms. Look for inspiration pictures and create an idea book, then use what you like to help you choose rugs, drapes and bedding before choosing the paint colour. Do you have any existing art that you want to use? That could give you clues for fabric colours and style. I wouldn't use the same colour scheme for the two bedrooms, exactly, although I might try to make them look similar by using some colours in common and keeping them in the same style. On the other hand, if you have a child who has strong ideas I'd say let him or her have considerable say in the matter for that bedroom (just this side of reason).

If I am having trouble finding a rectangle glass top table I usually order the glass from a local (to the location of my Client) glass shop and then the base from one of my furniture vendors. a dark table with your light chairs should not feel dark given that it is in a room with what looks to be lots of light with the large glass door and side window. I do think the glass would be perfect for the area. What size table are you thinking will fit the best in the space and for your needs?
