Who doesn't need a little backyard bungalow? A prefab modern escape hatch? With the Kithaus K3 ($44,900) you can have just that. The KitHaus was designed by Tom Sandonato and Martin Wehmann, and can be quickly constructed anywhere, without heavy equipment, thanks to its ingenious clamping construction system The Kithaus is built with eco-friendly components, is fully insulated, prewired, includes decks, canopies, and louvers, and has an optional solar component. The bad news, however, is that the price of the full-bling Kithaus package (which only measures in at 9-x-13 square feet) comes out to about $380 per square foot. That's over $250 more per square foot than what most US houses take to build. Still, if I had the cash, I'd welcome one of these little prefab wonders into my yard. How about you?
