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.

practicallity wise with young kids shaggy is going to be a nightmare ..wool is good as warm in Winter..and hypoallergenic.. Harvey Norman have great rug sales sometimes 40% off just keep an eye out for them.. I don't buy wool I just buy what looks nice and is practical.. 2 of my kids have eczema and they find wool rugs rough and itchy..we used to have a wool rug at our old place..so I only buy synthetic now..

Very unique. Hope you found it!

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.?
