This photo appears to have been taken around 1905 when Whitstone Road was newly built.
On the back of the photo it says builder of Whitstone Road (red brick) Alexander McMullen. See link below for a photo of Alexander McMullen and his son.
Behind the shop run by Miss H McMullen was Diana Street, nowadays it is Glanmor Park Avenue.
The children form an interesting group, see link below for an enlargement of this part of the photo.
