DROP box comes from Barcelona-based designers Manel Duró and Marta Gordillo who run the creative studio intenta. Although it's technically a "modular hotel suite aimed at the tourism sector", it would also work very well as a tiny home.
According to intenta, it is designed to have little/no impact on the environment, with modules built off-site out of wood. There are currently two models, one for two adults, one for a family of four, with either one or two bedrooms, bathroom with shower, and outdoor terrace. "The space is covered by large windows that removes the barriers of indoor and outdoor and help to fully immerse travellers into the natural world outside," sayd the designers.
There's an excellent 360 degree exploration of it at their site here.
