The Flintstone House is a house in Hillsborough, California overlooking, and best seen from, Interstate 280. It was designed by architect William Nicholson and built in 1976 as an experiment in new building materials, in the form of a series of domes. It was constructed by spraying gunite onto steel rebar and wire mesh frames over inflated balloons. During its early existence it was off-white in color, but was repainted a deep orange in the mid 2000s.

1976 was just the start of this one, I remember it being built back then.
It got a few more color changes over the years but was always originally a white paint. In fact when it was new we called it the igloo, because that's what it looked like.
