Dragspelhuset, an amorphous cabin in Årjäng, Sweden, with retractable extension to accommodate building codes near water in Sweden. Its environmental footprint is small: cooking is by propane gas; heating by a wood-fueled stove, whose chimney sticks out of the house’s retracting head; and the lavatory is a hut, without so much as a septic tank, reached via a path through the trees. The building is built from certified wood only, all structural wood an interior finishes from local supply. The stream feeds a hot-tub and is used for bathing; the bath water is heated by an underwater wood stove. The lighting is powered by solar panels, and the sense of space far greater than you might imagine.
