Its latest model in this style is named the Marie Ange and comes packing solar panels and underfloor heating too.

The Marie Ange measures 6 m (19.6 ft) in length and is based on a standard double-axle trailer, with a Douglas fir exterior and polycarbonate accenting. Looks-wise, it is very similar to previous efforts from the French firm and weight comes in at 3,300 kg (7,275 lb).

The interior floorspace measures roughly 19 sq m (204 sq ft). On entering the home, the living room is located to the right and looks light-filled thanks to its generous glazing. A small work desk nearby is connected to a storage-integrated staircase and leads up to the home's only bedroom.

The bedroom itself is a typical tiny house-style loft bedroom space topped by that headline-grabbing sliding roof, which allows the owner to sleep under the sun or stars if the weather allows – or, as Optinid suggests – make the bed in comfort, without banging their heads on the low ceiling. The roof is manually operated and slides on rails, and is secured into place with a series of clasps.

Elsewhere on the ground floor lies a kitchen with a sink and cabinetry, and space ready for an oven and fridge to be added. This connects to a small bathroom that contains a shower, sink, and toilet.

The Marie Ange gets its power from a standard RV-style hookup, but a solar panel array consisting of two 300-W panels helps reduce its draw on the grid (there are no batteries installed so it can't run off-the-grid). Heating comes from an underfloor heating system, like Minimaliste's Laurier, and should help keep toes toasty throughout winter.
