I lived in a very similar house in Yardley and my nan lived in one the same in Sparkbrook. I understood they were Victorian, so build sometime late 1800'ssearly 1900's.
I lived in Ash Road from 1955. We were at the bottom of Hall Road and could see to the top from our flats. The houses haven't changed at all except fopr the corner of Hall and Ash. There is a previous thread on the bombing during WW2 in Ash Road and Hall Road
