Am I right to think there's a difference in the house between these two pictures (1962 and 1980s)?

I think I heard the toilet extension had been built at a rather later stage (but when?)

29/10/2014. This is what Jo added concerning the first picture:

The picture of Helene and you beside the ferns was taken from the back door of No. 9. I am pretty certain that the toilet extension, as you call it, wasn't built until quite some time after that. It was definitely not before 1962 when I left home.

Hi a sort of little game: can you identify the objects circled on this picture?

I wondered whether the sort of box might be the same (or one of the same) as this one:

What do you think?? Then there's the other object which is on the cushion of the high chair: any idea?? And what about the frame on the wall? I think it's a mirror... Does anybody know if it's still somewhere?
