This was very, very cool.
So Simon and Darwin are playing video games and I looked in... and I saw a door I hadn't noticed before.
And from the back, you can see how big that attached room is. It's like a barn or shed now, but it might have been the kitchen back in the day. It has a big fireplace on the end farthest from the house, and the big room where the boys are playing could easily have been the dining room. Maybe.
This house wasn't lived in since the 19th century, until about ten years ago. So it might have stood empty for the entire 20th century. Little clues here and there.
