Why do respected environmental metrics like LEED for Homes, Energy Star and NAHB Green prefer manufactured homes? Because with pre-fab: material conservation typically results in less than 2% waste; tighter construction and shorter travel costs prompt energy conservation; fewer trucks and deliveries reduce degradation and pollution of the site; OSHA regulations and a controlled building environment provide healthier work conditions; and better construction methods means a longer life cycle. And naturally, pre-fab can deliver sustainable homes at lower prices! But, this new approach to building light on the land requires new design strategies. Students will learn to use SketchUp software to prototype a green, factory-friendly design for fast pricing. We cover how to “shop” manufacturers, and factory visits provide insight into their methods. At the end of the course all students will have a design with a strategy to maximize this affordable green architecture.

As in all Yestermorrow curricula, this course will focus on both design and building (construction). Within a few overloaded days, we will present a design/build technique that you can use to create your own custom, green, prefab home. It is important to remember that the prefab delivery method is presented entirely as a method for realizing your design vision - not the other way around.

Design is not linear, it's reiterative. We arrive at final design solutions by cycling through variations; assessing each alternative and then moving forward. It is not likely that the design solution accomplished in this short week will be your final design. That is not the point of the studio. Rather the main take-home from your time here will be a process that you can repeat and review as much as needed to arrive at your final, "perfect" design. If we can cajole you through this process just once in the few days we have, you will be able to build on it for months and years as you go forward.

Manufacturing houses and house parts off-site is not a new idea. The first prefabs were timber frames shipped by British missionaries all over the world. Since then, large and small parts of residential structures have been manufactured and marketed in every imaginable format. Sears & Robuck made a successful venture of prefabricated homes in the 1800s. After the WW2, the U.S. government funded Operation Breakthrough which spawned dozens of manufacturing initiatives, some of which are still with us today. Prefabricated kitchens have become the norm in most homes built today, prefab or otherwise. And virtually all windows and doors, originally built one at a time, are now sophisticated products from the assembly line.

The combination of passing time, shrinking resources and a new generation of homeowners has led to the current resurgence in this house making approach. This is currently the very best way to get a green, custom home that fits your site and your lifestyle while maintaining an affordable budget. But it is not "free lunch". It will rarely reduce first costs by more than 20% and the lead time is often about the same as that for a stick built home. What's most distinctive about prefab delivery is the predictability. Once designed, the price does not increase and the schedule does not creep.
