I remember the Fram. A pre-cast concrete producer. I used to go there to get sawdust for my rabbit cage (My father wouldn't let me in the house!! )
I moved miles from Colwinstone Street to the top end of Aberporth Road (About 600 yds) when I was 10 but having crossed College road I was no longer considered a Landaff northian!! I can't remember when they got rid of the fram but it is now Colwinstone close.
The pair of semis next to the field gate above that close were built in the mid fifties when the Fram was still operating.
