I have to admit that in the past I have been less than optimistic about modern prefab houses. Very few of them end up being priced at less than $200 a square foot. To me $100 a square foot is the magic number to try and hit before you can really claim it's "affordable". The 100k house is proving that it can be done with fairly typical building practices and a little creativity. So where does that leave prefab? Well not everyone has given up on it like I have, and the NY Times had an interesting article about a prefab modern home built in the Los Angeles area for $125 a square foot. The home shows some obvious influence from the Eames Case Study home and shows that using prefab techniques to achieve an affordable modern home might still be a possibility.
