But those residential blocks look to have been built in the late 60s or
mid-70s perhaps. You don't see dirt floors in mid-20th century
constructions, at least not in my USA.
I grew up in Holland (Nuenen, a ?bedroom community?), in a house built as part of a
subdivision around 1960. It had a tiny concrete-floored basement, more like a small
pantry a few feet down under the stairway. But the rest of the ground floor was built
over a crawl space that had concrete foundations but just the original dirt for its
floor.
