We've covered the Empyrean NextHouse in Silicon Valley before; here's a new story about the home from the San Jose Mercury News:

The 2,400-square-foot house was built in panels by manufacturer Empyrean at its factory in Acton, Mass., shipped to the Bay Area and assembled on-site. It incorporates energy-efficient technology and sustainable materials and is the seventh in a series called the NextHouse; the project has been a collaboration with San Francisco-based Dwell magazine, which has 12 more under way across the country.

Lots of people think prefab equals one-size-fits-all.

"Prefab is somewhere in the middle between the builder home, which is like a pair of jeans that's made for the average person, and the custom home, which is like a couture item," says Sam Grawe, editor in chief at Dwell, which has been promoting modern prefab architecture since its debut more than seven years ago.

"Prefab gives you the opportunity to design your own home but also has the efficiencies of the builder's model."
