I can see you like minimal furniture and clean lines so I will remember this when I comment. You are getting a new bigger tv, which I think would help balance the wall/tv ratio which is great, would you consider a long, low entertainment unit? Regardless that your tv is mounted. Have a look at this website; www.sydneyside.net.au Also, I do like the dark rug (recently bought a dark charcoal one myself) but it looks too small for the space. The next size would have worked better. Sizing is everything with rugs.

Absolutely agree with blueskies60 ! Remove the artwork/bench/plant that's on the left and replace then with either a bookshelf or a tall chest of drawers. Perhaps the plant can be repositioned into the corner on the floor where this troublesome niche is (there seems to be more than enough light there for a plant) and just place something calm and simple in the niche itself - perhaps a Japanese style scroll or pen and ink art work set off with a more rounded object sitting in the left corner of the niche; a gorgeous rock, a lovely candle, a calming statue... If you have (my preference) a chest of timber drawers on the left where the current art work is, you'll break up the symmetry, have more storage and have another surface upon which you can place a changing display of objects. This is the area that I would utilise for a mirror.

Silk would be interesting, not to mention elegant. As for paints, the Silver Illusion appeals, but it might throw green (not sure). I also agree the Tranquil Retreat is a good one. I'm wondering how big the feature wall is, and what is going on this wall, eg TV, fireplace, large artwork, etc.?

Depends a little bit on the style of your house , but my first reaction is the same as bigreader -- no , and almost certainly no , no , no , no , not 4 rooms in one house . Some of the schists look alright , the 80's style might suit an 80's or even 50's minimalist American house . There are some fairly cool 'wavy' panels that are available these days ; even some feature walls that look like timber ends sticking out of a wall ; wallpaper works in some places ; but one wall of brighter paint is the most obvious 'feature wall' . Faux Stone , or that ship-lap timber , or diagonal timber are about as exciting as yellowy beige or mission brown .
