I would be inclined to go with an unobtrusive light since it's the living room and anything too dramatic or a hanging pendant may interfere with your peripheral vision (or otherwise be an annoyance) when you're watching TV, etc. Also, being so near the sliding door, the wind may cause a hanging pendant to swing quite a bit which will cause the lighting to be constantly shifting and changing which I would personally find annoying. I'd go with something simple and subtle, but look at getting a tall standing lamp for the corner near the sofa (or possibly at the other end of the floating TV cabinet). In terms of warming up the apartment, I think you need something on the bare walls. A smaller picture above the floating TV cabinet will help to take the focus off your TV. A larger art work behind the sofa will also help to add some colour and personality, especially if it picks up some hues from your sofa. If you don't like the little Buddha statue, I would look at adding one or two other items that you do like (perhaps picking up colours from the wall art) and making a little vignette. A couple of colourful cushions and a storage solution for the wires, games console, etc on the floor would also help to bring everything together. Something as simple as a woven basket under the floating TV cabinet might help to keep the games console, etc in place unless it is in use.

I love nature so I saw the mountains first, then the flat roof, then the rain chains, then the glass walls, then the man, then the dog, then the whole picture. Quite a pleasing aesthetic overall. ...and Chook, I'd like to know WHY you are up on the roof in the first place!

So, what color did you eventually choose? I am really interested because the house we have just bought has similar color ceilings. I was also wondering about the color of the light fittings. I think that I will get some color changing LED light bulbs and have them installed all around the house. I like them more because you can both use them as a regular bulb or change the color to any you would like. It is also possible to control them using an app on my phone, making it so easy to control them. Now I think that it would be the most reasonable decision if I installed white bulb fittings so they look good with all the colors the bulb can make.

I would suggest that if you don't want to make mistakes in your house then you engage a design professional to get it right, especially if you don't know what you are doing. There is an art and science to good kitchen design, and there are plenty of bad kitchens out there which have been "designed" by amateurs. Kitchens are expensive to build, and most cabinetmakers will build with the plans they are given - they usually don't want to try and correct client's mistakes. Just because you can draw it, doesn't mean it will work. I know how to use a keyboard, but I don't know how to write a best-selling novel. Best of luck, Dr Retro of Dr Retro House Calls
