This is not your average conservatory added on to the back of a house. This is the John Nield Conservatory, which is effectively a hothouse in which exotic plants grow. A sign over the entrance tells how it was "erected and furnished with plants from the legacy left to Stamford Park by the late John Nield Esq. J.P. Apsley House, Ashton under Lyne, Opened 3rd Oct 1907."
I showed you a photo looking up at the roof structure inside the conservatory three years ago.
