Is this still the Student's Union. Any time I've been past, it's looked more like a derelict building, though that could just be the side nearest Rope Walk.

Does this cycle path connect up with the other residential streets that end along here?

There's a small post beside the post box suggesting that there's possibly a foot path starting here across the field.

Road sign mentioning Rectory Road here, with Primrose Hill under it. Based on Video going along Harwich Road.
