They don't build houses like they used to. On a more serious note, there is a house open to the public in Dallas that was built with 3 foot concrete walls. The name of the original owner escapes me, but he was a geophysicist, IIRC. Anyway, the library was incredible. It was huge with large windows to let in the light, a large fireplace in the middle of one of the long walls and plenty of built-in shelves. The square footage (of the library, never mind the rest of the house) was probably more than any residence I have ever lived in. Plus it had a secret room in one of the corners. What fun!
Sheesh...what were they expecting in Dallas, Santa Ana to return? When was that house built?
