Wired just posted a list of their picks for the best "small and fabulous" modular, prefab homes. Our favorite? The Miesian style of the gorgeous (and pricey) structures by Marmol Radziner shown here - followed by the nearly unbelievable perch-like Single Hauz from Poland (just below):
Totally Custom: weeStudio from weeHouse/Alchemy Architects. Lots of options to choose from. Sized from 350-660 sq. feet.
Temporary but Cool: Icosa Pods by Sanford Ponder. $2,150 per pod and "snaps together like Legos".
Beach Bungalow: A $100/sq foot vacation home - Versadome.
Rooftop Helicopter Delivery: The Loftcube by Werner Aisslinger.
The Smallest: MD-42 (42 sq. feet) by Edgar Blazona and Brice Gamble. From Modular Dwellings.
