Ada at Walsingham Lodge

The first picture show Ada Mackie standing in an arched doorway. Written on the back is "Walsingham Lodge, Chislehurst. During the War. 'Mum.'" The photographer must be her son Jack, more often behind the camera than in front of it. The fact that it says "during the war" highlights that the print was made some time later. That's also Ada standing in a doorway shading her eyes. I do not recognise the location and she is wearing a different dress. I think that is also Ada in the next picture, but it is difficult to be certain as her face is in shadows. Again, she is dressed differently and I cannot identify the location. I am guessing the ivy-covered building could be 'Walsingham' but cannot say for certain.
