What's origin of diagonal room?

THERE is a small room placed at an angle on top of the two-storey building in Ring Road, Greenacres, which now houses Varsity College and a branch of the post office. I have been trying for some time through Facebook to see if anyone can enlighten me, but all I've established is that it may have been from the old Fairview race course that existed on the site before Greenacres was built around 1980.

Some believe it was the commentary box, or perhaps the place next to the finishing line from where the stipendiary stewards viewed proceedings. If that is so, then where was this little concrete room situated?

Was it part of a main spectators' stand and if so, at what point was the stand demolished and how did this remnant come to be saved? If it was saved, where was it kept, because the Ring Road buildings were only built much later, from around the mid-1980s if my memory serves me well.

Why was it kept and which developer decided he wanted to see it perched on top of his building? Is it meant to serve as a reminder of those days? If so, where is the plaque giving us the story?

The Nelson Mandela Bay municipal website says: "Prior to 1850 irregular thoroughbred horse racing took place in Port Elizabeth but it was officially started in 1857 when the PE Turf Club was formed. In order to establish set rules for racing, in 1882 the Jockey Club of South Africa was also founded in Port Elizabeth [another first for the city].

"The old Fairview Race Course, previously the PE Turf Club, was situated where the Greenacres shopping centre is today."

I've asked Varsity College and the people who own the building if they know how that little block came to be there, but without success. So if anyone has any useful information on the subject, I'm sure readers would be keen to learn more.
