Despite recent economic upheaval, owning a home is still a life goal for many people. In addition to finding a house in the right location that suits aesthetic desires, a growing number of consumers are concerned about impact of building materials and energy efficiency. There was a time when addressing these concerns meant a big uptick in cost, but increased availability of pre-fabricated eco-friendly home designs is changing that.

When some people hear pre-fab home, they instantly thing “double-wide” or a flimsy-looking cookie cutter house built from cheap materials. The reality is, pre-fabricated homes are becoming more sophisticated by the second. To help dispel any misconceptions, we’ve rounded up five amazing houses that you’d never guess were built in a factory.
