Back in the day, this really had made quite the show. I think it was built as a house and later converted or the person repurposed it

It would have been a manor house once. WW2 probably changed the goalposts. I find stained glass windows outside of churches strange.

I want to hear how you shimmied up that drainpipe again. When I read that, I knew you were crazy, then squeezing in a window?

It wasn't as bad as it sounds. Think of that homeless dude, who has to do it every day!
