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 cant remember back if 2 year olds can climb, but if they can you might need a smooth finish so they have nothing to grip and climb,I would also suggest a sign making company they do a thing product called acrylic or corrugated ,this cut to size would also do they would need to drill holes in the acrylic for you possibly

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
