I think the curved bit is the entrance up into the wagon..maybe an old shara, converted.

I'm beginning to think maybe 1931/2 now as my uncle is in long pants so probably left school...
And there is a washing line at the back so habited housing and not works or a warehouse.

Wasn't the hippadrome a wooden building?

I also seem to see some mock tudor type beams....
