I have to comment. That's huge! Way bigger than most UK Victorian 2 up, 2 down terraces. More like the size expected in an older 4 bedroom house if you ignore the extra space the photographer is clearly standing in.

Have a random right move link of what I think as typical Victorian worker's terrace: https://www.rightmove.co.uk/property-for-sale/property-62228...

The door by the yellow chair is a tiny porch with front door beyond. No idea how it compares with OP's.
