Look up!
Quite a few years ago I found myself outside a pub in Manchester, consoling a remarkably good looking woman after she had argued with her boyfriend and, for reasons that are now beyond me, explaining how she was like a tree growing on the ledge of a building opposite.
From then on, I begun to look for trees gaining a foothold in precarious places; I see it as a sign of hope somehow.
Then a couple of years back I read some research which suggested that the vast majority of city dwellers never look beyond the first couple of floors of the buildings that surround us all.
Hence, I started this site – looking up shows a different face to buildings. Quite often there will be interesting or unusual features and occasionally – a tree!
If you spot a building where nature is regaining a foothold then let me know – send a picture and tell us all about where you saw it!
