Well, I'm still recovering from the nasty postwar housing I was raised in, back in the San Fernando Valley in the 1950s. The first house I remember properly (I have a few vague and disconnected memories of the previous) was one we moved into, newly-built, in 1955--we subsequently lived in two others within a half-mile radius, each differing in exterior details but identical as to floorplan, by 1962. I thought at the time that everyone lived that way. Two of those three houses wre bulldozed before they turned twenty for what is now called the "Ronald Reagan Freeway." I now own a house built in 1908. I'm confident it will still be standing in fifty years. I doubt whether the single remaining SFV house from my childhood (I visited the neighborhood the other year--a slum) will survive as long.
cordially,
