The categories of housing as described in the first reading was quite interesting the author broke it down in exactly what he wanted to cover in his book. The notion of the first of anything to be produced that costs an amazing amount over the cost of what it sells for (like when the talk of Fords first concept car was introduced) was a big factor for a long time. I feel with 3d design software and so many things in the production of any real manufactured good really brings that cost now down. I was surprised to read about, what I understood as the writers doubts that, mass production housings possibity. Today we still find very similar modes of building from the develop that creates a “cookie cutter” set of houses with all very similar style and aspects, to the moble homes and pre fabricated erector set homes and things have not changed a bit. The author goes on to say that the housing industry is 5000 years behind the auto industry in the ability to mass produce housing. It seems right we are still building houses in generally the same way we have done about the 1900 but car production has  really changed.
