Lots of ideas....couldn't resist adding my two cents. i copied your photos and did a little cut and paste- it's messy, but hopefully gets the main idea across. i'd put your sofa in front of the large book case, chair by the fireplace, tv on the stand on the wall opposite the fireplace - so you can either look at the fire or the tv. Someone suggested using frames of one color for your photos - an inexpensive way to do that would be to spray paint them all a dark color-black goes with everything. Since your shelves are a medium tone wood, display things that are dark or light so that they contrast against the wood. Limiting your display items pallette to a few values usually helps to unify things. (I think that's why so many people want to paint the shelves or put inserts in the back to help your nice things read more clearly...some get lost). If you want to "splurge" -you may consider having a carpenter make a few solid tall cabinet doors to provide a visual break in the shelving. I'm showing 3 doors - 1 on the right side of the fireplace and 2 on the left to leave two open vertical shelves for display on each side - with things arranged to frame the fireplace as the focal point. To add some height to your big vases, consider stacking some books beneath them. Enjoy experimenting untill you get something you're happy with - good luck!

I would also definitely go white if the windows are on the green wall. Will be much more natural to tie the accent wall with the stark wht contrasting walls. Always a very chic contemporary look. Also very relaxing as opposed to the treatments standing out when you already have your standout feature- the green accent wall. Great white bed you ordered! Then I love all the blue/green/ silver accent advice. I did a similar room in purples/greys/ whites and we used great posted prints of florals with a little oriental flair in nice big mats w frames. You could do florals or nice big botanicals in greens would be very fresh and modern!! White or silver frames or maybe even the shock of black would be cool.

The rules may have changed but when we built our extension the wall adjoining our neighbour had to be completely within our own boundary. It looks as if your neighbour has continued along the party wall and therefore half the depth of the wall is on your land. It might be worth getting a chartered building surveyor to check it out as otherwise it may cause difficulties when either you or your neighbour come to sell. If I'm wrong about this maybe a professional on here could correct me. Other than that I think you should make the best of the little private courtyard it has afforded you by using plants in pots and climbers to soften the wall.

I have large concrete walls in my living room, also a lot of pictures which I'd like to display. Am loathe to drill holes in the wall for nails for individual pictures. Ideas which will not deface the walls too much would be appreciated. Thanking you, Noreen
