The first house I bought was a one-up-one-down back-to-back brick terrace house of 328sf.
It was a great bachelor pad. I found out from a neighbour that back in the '60's is was occupied by a woman and her four children!
Heating was a single woodburner which did double duty as cookstove.
I bought it for 18.5k and sold it ten years later for a cool 100k.
My home now is a 120 year old stone built end of terrace house of 700sf plus cellars. I love it.
