How to brighten up a blank wall
I live in one of a row of identical bungalows. The kitchen window looks out at the blank side (apex) wall of my neighbours house, which is I guess 3m away. So I have a small courtyard outside the back door. The sun shines directly into the space for perhaps an hour at midday, but otherwise the light is quite good, I manage to grow stuff in pots under the kitchen window - but of course I don't see these from indoors.
I want to put structure up to look at. I thought of trellis panels. There are a few restrictions (mine) on the design.
Nothing should be directly attached to my neighbours wall. The 'structure' must be self supporting - although I could brace it in a couple of places. There are several screws / nails / vine eyes in the wall suggesting that previous owners of my house had at some time grown a climber there. (the bungalow was built in 1950). I did attempt to brighten the space with Spanish pots as you see from the photo!
I don't want to put permanent planting - e.g. a climber - there. (Risk of damp affecting the wall.) I had thought of trellis that I could attach pots to for summer geraniums for example.
There's a restriction on the depth of any structure/planting because the courtyard is also the way to the back garden and I don't want to narrow the gap too much.
