For many, the idea of prefab may bring to mind trailers and other less desirable images of housing.Instead, the new prefab is becoming the inevitable next step to "cool" housing as home buyers look for distinctive yet reasonably priced first and second homes. One in six new houses today is a prefab and 400,000 units are now produced in the U.S. each year. More than 50% of all homes are constructed in whole or in part by using building systems -- modular, panelized components produced in quality controlled environments. This exploration of the best prefabricated houses on the market today, from all over the world, along with a resource directory on how you can purchase them, is an invaluable reference for those interested in this alternative.
