There is perfect competition in tiny house market so it’s much tricky for firms to stand out until or unless they offer something different. Therefor France’s Optinid offers something different with its line of models that open up the bedrooms to the elements with sunroof-kind sliding roofs having the sleeping capacity of six persons.
Named as Stéphanie (after its owner name), it measures 6 m (19.7)-long and 2.55 m (8.3 ft)-wide, having height of 4 m (13 ft) with a total floorspace of 20.4 sq m (220 sq ft) whereas its clad in fir and interior is finished in painted spruce. 
Entering the living there is sofa bed that sleeps two while above small loft space also sleeps which is reachable by ladder. There is combined office/music space adjacent to the living room. Additionally, office has storage space for sewing machine and it leads to the bedroom by integrating the staircase.
It’s pretty impressive that French tiny house Stéphanie sleeps a half dozen which is equipped with bedroom, sofa bed and secondary loft. While the roof in the bedroom is similar to Optinid’s previous models that can be unlocked and slid open on rails if the weather suits but now it has been transformed by the firm into a smaller and lighter tiny house as compared to previous models.
If we talk about the small kitchen then there is an oven, a two-burner induction stove, a sink, and storage space as well. Kitchen pantry is connected to a fresh air circulation system whereas the small retractable table provides enough dining space. There is snug bathroom with a shower and dry toilet at the far end of the tiny home.
The Stephanie uses ground-based solar power array for electricity whereas hot water comes from an electric water heater. Stéphanie’s price not yet finalized however firm’s similar Cécile cost is around 62000US$.
