I love tiny houses but even more if they are designed to be sustainable, energy-efficient, and on wheels – that is exactly what Project Ursa is! The mobile home is made for off-the-grid living featuring solar panels, water harvesting systems, and the coziest interiors that makes the “cabin in the woods” aesthetic into a lifestyle.

Tiny houses on wheels have to have a length of 4m, 5m, and respectively 7m, to be 2,5m wide and to have a maximum height of 4m. The Ursa tiny house is currently located in Cascais, Portugal, and can function completely off-grid.

To ensure that, the roof features a subtle 5% slope which allows rainwater to drain easily into a couple of water tanks with a total capacity of 650 liters. This water is then redirected to the kitchen sink, the bathroom sink, and the shower where it’s filtered and reused. After that, the reused water goes into another tank and from there is used for watering plants.

On top of the roof, Ursa features solar panels which are facing South. Their inclination can be adjusted up to 30% in order to maximize the energy product all year round, making this a very efficient off-grid tiny house.

The energy produced by these solar panels is being converted and stored for later uses so the inhabitants can always have energy on demand when needed. Check out our informational article covering solar panel companies if you’re interesting in this subject.

This tiny house offers 17 square meters of living space in total which is organized into a kitchen, a full bathroom with a dry toilet that produces compost, a living area, two sleeping areas, and also an outdoor deck. Of course, each of these spaces is small and they all blend into one another which creates a cozy ambiance inside. This is accentuated by the warmth of the wood used for both the interior and the exterior of the Ursa tiny house.
