On the other end of the spectrum (from my previous entry).

Inhabitat :: Rocio Romero's LV Home

At 1150 square feet, the LV Home has two bedrooms, two baths, and an open living plan. And the cost? The basic package, which contains wall panels, structure, and cladding, will run you about $32,900. Once finished out, this clean, modern box totals around $87 per sq-ft.

Wonderful.
