Blue plaque hunting

I managed to escape for a lunchtime outside in the sun sitting on a bench by Fitzroy Square. The gardens are open some days but were closed today. I sat and read my Kindle while eating my sandwich. I noticed the blue plaque on the building opposite and was just about to go and take a closer look when a film crew arrived and started rehearsing a walking shot right in front of the building. It looks as if George Bernard Shaw also lived at this house.
