Just have a look on google maps, you will get to see everything very clearly in streetview.
I live around 200yards from runcorn road, in moseley.
Ladypool road (balsall heath) is a 1 mile street full of grocers and restaurants which connects stratford road (sparkbrook) to moseley. Ladypool road runs parallel with alcester road, which joins the south city centre (highgate!!) all the way to outskirts of the city (druids heath etc) where it begins to get slightly rural (horses etc).
Runcorn road, connects ladypool road and alcester road at a right angle. It is solid rows of compact terraced housing with a few courtyard/squares towards one end, which contain more tiny homes.
The balsall heath, sparkbrook & sparkhill areas are mainly inhabited by people of south asian origin, 3rd generation immigrants. Im told by older local people, that ladypool road used to be very run down in the early 1970's with a lot of closed shops/abandoned buildings. The new people came and made the grocers and restaurants, and it is now thriving with well-kitted out independent businesses.
The homes are in very high demand, runcorn road is very popular with bangladeshi's who run the restaurants. It is common to find two families or more sharing the tiny terraced houses.
There is no signs of any grocery store actually on runcorn road. There is also not many old things still in highgate. Highgate is mainly 1960's-70's high rise flats and cheap/bad housing estates stuck in between the big roads that enter the city centre. There are ugly schools, shops and churches from the 60's and 70's too. A lot of it is being knokced down, but there is little new being put in its place.
