visited Liverpool university yesterday and saw some interesting stuff. loads of money being spent on the new buildings and ended up watching my feet and looking at surfaces. realized what an eclectic mix of paving they had used. Also many of the street trees have had tarmac placed right up against their trunks! how long will they and the paving last I wonder
nice example of a green wall, clearly no problem with irrigation as it poured down all day
sadly most of my photos didn't come out well due to the weather so heres a post of some  nice  concrete seating and  ginkgo trees
