A red square is a shop sign. Apparently there are a number of these "friendly shops" around in ZA, unfortunately they don't have website and Google Maps does not list all of them. You can also see part of the text on the building "*ville mansions". Again, Google Maps does not have this building nor Bing/OpenStreetmaps, but still it's possible that there is some sort of registry of ZA businesses which you could query to get potential addresses. It is also clearly spring on the second photo and the shadows are well defined, so you can approximate time of day (midday) and street directions (shadows point north or so). You can see that these are four way crossroads with at least one road being just two lanes wide, there are at least two buildings on the corners and along one side of the road there is a longish green zone / possibly a park. I think there is a bus stop on the road with the park as well. Not sure what are the FH markings on that yellow thingy and what's that blue square with yellow something. These might be street signs that are specific to some region/city, so just browsing random locations in ZA could turn something up.

This info wasn't enough for me to figure out the location, but it's something. If I was serious about the challenge or there was way to monetize this, I could write OpenStreetMaps / Google Street View scraper that would figure out the location in a matter of minutes.
