I can't see anything on the picture by Fleetwoods Lane Ken, and that was 1952.
The early housing looks, to me, like Simon's Croft (just behind the hills) and some on one side of Gorsey Lane, Park Lane/ Bridge Lane semis, and the five semis on Fleetwoods Lane.
Ford and Netherton estates, the corpy housing, would be in the upper right quadrant of the photo. Just lots of grass.
There doesn't appear to be enough room to fit in two football pitches on the land in front of the hills.
You needed to be half mountain goat to play on the pitch at the Stand Park end.
Build up a lead kicking downhill in the first half ,then hang on for dear life in the second half.
I'll try and get an equivalent view of the area today for comparison
As for the annexe, I think it was a bit like St Martins on Stanley Road, lots of schools used them as temporary residence.
Holy Ghost had them from approx 1962.
The photos of the school football and cricket teams I posted were taken at the annexe.
Sterrix Lane school was immediately to the rear on the photos.
Don't know if it is an apocryphal story, but I heard the hills on both sides of the canal were erected to carry a link road between the Cabbage and Dunnings Bridge.
Bit like the story of the Princess Way bridge that was meant to go over the Hawthorne Road junction at the White House but someone got it wrong.
Edit. I can't replicate the exact view, but if you use the golf course and canal to get your bearings you'll have fun.
