A very rough guess but the whole of the estate between Grange and Newton along Frankby Road and Ennisdale Drive (with Ennisdale Drive complete by March 1958) was developed 1957-1958. I think the married quarters date from the same time. The contractor for the whole estate was William Farrell (w.j Farrell / Bill Farrell) who had built 1930s in Gleggside before the war.
