The Ljubljana, Slovenia-based OFIS Architects recently completed a unique cabin, which could serve as a tiny dwelling, a vacation home, housing for researchers, or even a shelter. It’s located near Ljubljana Castle, which is on a hill overlooking the city. It is the result of a joint effort between the companies Permiz, C+C, C28 and AKT Living Unit.

The project is aptly named Living Unit on Ljubljana Castle and features a flexible wooden shell that makes it easy to install it on nearly any kind of terrain. It’s also easy to transport pretty much anywhere. The basic version of the cabin is made up of three wooden volumes, which are designed to be stacked on top of each other. The cabin measures 14.7 by 8.2 by 8.8 ft (4.5 by 2.5 by 2.7 m), but since it is modular it can be expanded in size both vertically and horizontally. No foundation is required, but it does need to be anchored into place.

The volumes seem to be quite tiny, and the home features a kitchen and dining area on the ground floor, a sleeping area on the first floor and a lounge on the top floor, which is accessible by a ladder. The kitchen features a sink and stove, and a storage unit, which can also be used as a ladder leads up to the next floor. The bathroom is next to the sleeping area, though it is not pictured here.

The volumes are quite tiny, but they are very functional, and solar panels, a composting toilet and a water filtration system would all be easily installed, then this cabin would be completely independent of the grid.

The Living Unit on Ljubljana Castle is currently a temporary library, and is open to the public from 5.30-9.30 PM every day through August 14. There is no word yet on pricing, though this will likely be released soon.
