Here are a couple of images from the house I grew up in. Most of Ilford in Essex was built up around the late 1800s, during the Victorian style of architecture.
I can remember I used to talk to my friend who lived next door through our bedroom walls.
The second image clearly shows the outside toilet each house had, just adjacent to the kitchen door. Cold in the winter and not for those who don’t like spiders!
Long before soundproofing and cavity insulation was thought of. Also every house had a lovely tiled front path, I always remembered that.
