We don't see many tiny houses with green roofs, but Austria's Wohnwagon (translated as "living wagon") demonstrates that it can be done. Outfitted with distinctive, rounded ends and round porthole windows, the solar-powered tiny home also boasts its own water filtration system that cleans greywater for reuse -- using marsh plants on its roof.
Measuring 32.8 by 8.2 feet, the 269-square-foot Wohnwagon is built out of larch wood on the exterior, and spruce wood and clay plaster on the interior. The wagons are insulated with sheep's wool, while the green roof also provides an extra insulative boost, while also helping to filter the wagon's greywater run-off from showers and sinks, so that it can be recirculated and reused again for washing and drinking. Rainwater is also collected and stored in tanks underneath and on top of the home.
Another fascinating feature is the modern version of a wood-fueled water boiler-heater, traditionally known as a Badeofen. The bathroom features a natural stone sink and details.
For people who stubbornly want to stay in bed to feast or work, the sleeping area also has an extra fold-down table. A pull-out guest bed is conveniently hidden underneath the main bed.
The kitchen's two oak counters are rounded too, to continue the theme of curved surfaces.
Wohnwagons are made to order, and range in price from €40,000 to €90,000 (USD $43,000 to $95,600). For those who just want to try it out, it can also be booked as a room in the Almdorf Seinerzeit hotel in Kärnten, Austria. For more information, visit Wohnwagon.
