Just found this question. I lived on Belmont Terrace up until around 1980. VfOUR1965 is very accurate and I'm pretty sure I knew him, I'm guessing it's Paul. I'm Stefan and lived at number 19.
As others have said, Belmont Terrace was located between Clumber Street and West Hill Drive. You couldn't see it from clumber street because it was behind the shops and other buildings. To access Belmont Terrace by car, you had to go up the dirt road next to the amusement arcade (playland) on Clumber street. Belmont Terrace consisted of 20 houses and had a dirt road which led around the front and back. There was an archway between numbers 6 and 7, big enough to get a car through. Opposite the archway was a gate into the Lurchills.
There was waste ground to the front and a gravel car park. As kids, we'd play football in the car park, make swings in the trees and ride our bikes on the dirt track around the houses, cutting through the archway so we could do lap after lap. Those living there used to hang their washing out across the back, between the kitchen wall and the Lurchills wall, so understandably they weren't very happy if we were riding our bikes through their washing!
All the houses had an outside toilet, which was against the Lurchills wall. So if you needed the toilet, you had to go out the back door, through the small yard, cross the dirt track, just to use the toilet. It was freezing in winter in the 70s!
Gradually the council bought all the houses, we were the last to sell up and leave. They were knocking them down to build the ring road. I drive along the ring road where I once lived and try and guess where my house was. The row of houses was probably on the stretch of road that runs behind the disused nightclub and wilkos.
Have great memories of Belmont Terrace.
