I'm not a fan of wallpaper, though I'll admit there are some powder rooms on Houzz with beautiful, two-tone wallpaper that I love. The last time we bought a house we had to choose between two equally desirable, quite similar vintage houses--one with wallpaper on every wall (even in the hallways!) and one with painted walls throughout. In both cases we planned to repaint in colors of our choice, but we bought the house without the wallpaper because it was simply less work to repaint the painted walls than to strip a house full of someone else's tacky, outdated wallpaper. So by all means use wallpaper if you love it and will be in the home for awhile, but don't expect anyone else to appreciate it when you sell. Wallpaper (like patterned fabric) is just too individual a preference to translate easily into someone else's aesthetic.

Lovely print. I had a peacock feather print and I had a colour called glacier Grey behind. Think it was Wattyl . Again like your other walls it is a greenish grey but darker. I also had my prints on a charcoal wall..loved that too. As you said the picture ties in with the chairs and now it's not necessary to add more matching colours. I'd buy a couple of sample pots and paint large pieces of cardboard. With the other walls I would consider painting them in whisper white (Dulux) a very universal colour that ties in nicely with all colours.

Ok, the shop I'm referring to is called WallCandy & they have a branch in Sydney. Here are the details: Address:2 Danks Street, Waterloo 2017 Phone:(02) 9331 5884 Email:sydney@wallcandywallpaper.com.au

The mirrored wall certainly gives you a 'wow' factor and the floor is stunning. I wouldn't do a textured wall paper or metallic, I think you'd end up with too much going on in a small space. If anything I would perhaps paint the white wall in a very light grey to pick up the grout in the floor tiles.
