Mobility is above all the ability to start a movement without unnecessary delays and complicated preparations. The house provides the opportunity to quickly set off after attaching a trailer behind the car. On a camp site, the external wall, which forms a translucent accordion, rises to illuminate the interior, increase the amount of air in the house, and expand the space. The self-sufficient house produces electricity using photovoltaics located on the roof. Pneumatic accordion-raising pistons tilt the roof to follow the sun, increasing the efficiency of the off-the-grid system. In „Hose“, one enjoys the benefits of traveling and the comfort of home at the same time, and thanks to this, can travel anywhereas long as he wants.
