My grandfather next door and my Dad built house I grew up in in 1948, 97yo Mom still lives there. It has that double door about 2ft square from patio to utility room for milk deliveries. Another guy delivered eggs & butter. My grandparents house was built in 1940 and has a coal chute in basement we used to slide down as kids. That house was built with a very large tank in attic with a skylight over it. It's open, a gravity system filled by a spring powered by hydraulic ram in the creek. You could draw a glass of water and sometimes a dead wasp would come out!
My grandfather video taped construction company building a lot of it. I had a copy made to VHS years ago and gave it to the company, still in business and really appreciated it for historical records. Grandfather panned it around at one point and the neighbor was plowing a cornfield with oxen. I have a very old large farm bell by the door here given many years ago, the bell neighbor's grandparents used to call in their slaves. He had 2500 acres given to ancestors from the UK King at the time.
Lots of memories!
