From Apartment Therapy:

If you're heading out to the desert for Modernism Week and are curious about prefabs, you've got a chance to see a drop dead gorgeous one.... The Desert Prefab house has been called possibly the most beautiful prefabricated building this side of the Pacific, and it's for sale!

More detail on the house from the LA Times:

It is the house that won new respect for factory-built prefab housing: Leo Marmol's sleek, solar-powered, steel-and-glass Desert House in Desert Hot Springs, Calif. It has been Marmol's weekend house since he built it in 2005, but it is now listed for sale for $1.85 million....

The L-shaped house is the prototype for Marmol Radziner Prefab, an architecture and design firm based in Los Angeles. Framed with recycled steel, it features teak cabinets, concrete floors tinted the color of desert sand and glass walls. It consists of 10 modules in all -- four house modules and six deck modules, to encourage outdoor living. The three-bedroom house features a guest wing with studio space, partially shaded decks, a swimming pool and sweeping mountain views.

And a sales pitch from the real estate listing:

First Offering: The Desert House, 2005. Art, architecture and environmental awareness have been forged together in Marmol-Radziner's custom prototype for their burgeoning prefab division.... From the two-parcel, nearly 7.5 acre site on which the main house, guest house, studio and nearly 2,400 square feet of outdoor decks reside, broad panoramic vistas across the pool capture the all encompassing desert floor sweeping out to towering Mount San Jacinto and San Gorgonio.
