Because the style is quite modern eclectic, my thought was that a muted cow hide rug could work If you feel a bit more daring - these muted colours would echo the traditional carpet or failing that go for a high sheen textural rug that doesn't compete with the monochrome elegance

We have installed wallpaper behind glass splash backs on many occasions without any problems, the glass usually being attached by a thin beading of clear silicon applied around the inside perimeter of he glass, then fitted the day after the wallpaper install. MOST importantly the INSIDE of the glass be kept perfectly clean on install as even fingerprints will stand out

I agree paint may be more versatile - but the right wallpaper on a feature wall with that deer head would be so freaking awesome ! Depending on your colour scheme, if you go with a vintage or art deco pattern, fairly subtle and with a slight texture in it, that'll beautifully offset the deer. And if it's the right choice then you won't want to change it for the next few years anyway. So definitely wallpaper - there's some great 'wall candy' around :-) Good Luck !

You're welcome! Roof/city scapes are like landscapes, but the views are of roofs not plants. Google roofscapes images and you'll get the idea : ) And if you're not bothered by the roof next door then I'm not bothered by the roof next door! I'm sad to say though that your metal outside stairs idea will likely not get approval from your local Council. I say that approval is unlikely because that roof next door seems very close, so I imagine the setback of your house (and theirs) is likely as close as Council will let you get. In other words, no building of any structure such as stairs would be allowed in the space that's there now. But never say never...give their planning department a call or submit an enquiry online and just run the plan past them. Maybe instead of stairs you actually mean a Juliet balcony? (google it!) Even that plus the type of window it's attached to is subject to Council approval so again, you would need to contact them. Plants on a Juliet balcony would indeed be very charming but I'm not sure how realistic this option is. So all that being said, I'm still going for my roofscape/cityscape option to better incorporate next door's roof. Roofscapes can include trees too you know!
