At my age, many of my friends, including myself, have lost the birth house. The old houses were mostly built with wood and do not last long, in case of my birth house, it was more than 80 years old when demolished and reconstructed nearby site.
I still remember some details of the interior, like long narrow corridors that connected maze of small rooms. There was only one toilet place in the rather large house. During my junior high school days, I was on the second floor, and to get to the toilet took miles. I ended up pissing from the window time to time.
