"Broadly defined, a prefab home is a home composed of various parts, almost like Lego blocks, which are prefabricated or premade in a factory and then assembled on-site... 

Although such homes have long enjoyed popularity in countries like Sweden and Japan, only recently have they started to catch on in the U.S. thanks in part to a redefinition of the term 'prefab home'....

At the outset, the cost of a prefab home is fairly similar to the cost of any other custom home: Per square foot, prices generally range from $100 USD to $150 USD. The notable difference in cost is in the time required for construction... 

In fact, one of the most remarkable aspects of these homes is the drastic disparity in building time compared to a custom home. On-site construction of a custom home can easily take a year or even longer depending on a variety of factors -- like weather, for example.

Prefabs, on the other hand, can go up remarkably quick: Installation and the move can happen in a week's time. The numerous benefits to this are obvious, but consider this: If you own land in a desirable area -- i.e., Vale or Cabo -- you can start the process to have a sensational second home there in one season and enjoy it the next."
