Forget the fact that I lived in Japan and absolutely love its culture, I didn't know that Toyota had a homes unit. And they've been in the business of making homes for over twenty years! The company adapts automobile manufacturing technology to build stylish, earthquake-resistant homes for sale within Japan. The Toyota Homes unit accounts for only .5% of the company's $262 billion in annual sales, and Toyota would like to beef that up a little bit. Plus, with the roll-out of the plug-in hybrid beginning in 2010 (remember all that discussion here about solar homes and plug-in hybrids replacing gas stations?), Toyota would like to do more with their environmentally-friendly, prefabricated homes.
According to the Wall Street Journal, Toyota Homes are built from six or more modules in under 45 days. They have a conservative home model called the Smart Stage that sells for $200k. It's about a 1000 sf, two-story home. There's also a more expensive, custom-built 2600 sf home that sells for around $800k.
