On a beautiful sunny Wednesday a couple of weeks ago, one of my favourite things happened - I was already out with my camera gear and suddenly found myself with an hour free.
A chance to wander through the city, check out some new buildings and construction sites, and just enjoy the light playing across surfaces.
It seemed like it was a perfect afternoon for window cleaning too.
At 80 Fenchurch, one of the window cleaning team told me they are out every day, using one of three cradles or abseiling. I asked if the curved concave facade is problematic, and he told me the crew have to constantly manoeuvre themselves closer to clean.
