University College Hospital
This building looked like an office building to me but thanks to sjnewton I now know that it in fact is University College Hospital. I took this on my way to Camden Town. I was in a bus no 24 then.
The weather was really nice then. Sunny and lovely. And I loved the way this building was all blue and shiny. Obviously as I was in a bus (luckily the windows were clean) I didn't have a lot of choice about having or not having the street lamps etc. in the pic. But I think that the point of this pic is to marvel the fabulous colouring of the building and the glorious, sunny weather of London. ;)
