Vallisaari, a sun drenched island just a 15-minute ferry ride from Helsinki, recently played host to the Zero Travel Nolla Cabin.

The fetching a-frame, from Finland-based designer Robin Falck and Neste, is a concrete (or perhaps I should say wood and glass) as well as metaphorical lesson in sustainable living.

More specifically, the cabin is meant as a model for eco-conscious travel. Just 13 feel tall and eminently portable, Nolla is perched on stilts that leave the landscape untouched. The idea is that it can be built in any locale—without altering or damaging the surrounding eco-system—within two to seven days.

Nolla is a model for renewable power as well. Electricity is provided by a wall-sized solar panel mounted on the Northwest side for maximum solar gain. The compact Wallas stove satisfies both heating and cooking needs—it’s powered by Neste’s My Renewable Diesel, a diesel fuel made entirely of residue and waste.

Treading lightly is part and parcel of the Nolla philosophy, so rather than transporting the cabin to different locales, the company is staging a “Build Your Own Nolla Cabin Contest.” Entrants post a picture of the view they’d like to see from their proposed Nolla locale, framed in the triangular floor-to-ceiling window. 12 winners will receive blueprints and building instructions.
