I recall our first house in Atlanta, bought in 1964 (my parents did), four bedroom and about 2,000 sf. It's still there, I liked it because it had a half basement, which is unusual around here at that time, and a lot of woods behind it. I think it was $26,000.
Houses back then, even new ones, were small relative to the McMansions they build today. We marvel at the new subdivisions going in near where I play baseball, huge looking "estates" ... I'd guess they all have SubZero and Wolf gear in them.
