The architects from the Slovenian practice OFIS arhitekti, in collaboration with C+C, C28, and AKT, have developed a self-contained wooden shell, flexible and adaptable to different locations, climate conditions, and terrains. It can be used as a holiday cabin, hideaway, tree house, or short-time habitation for research, tourism or shelter. Moreover, small dimensions of the structure also allow easy and different transport possibilities.

The basic unit (4.5 x 2.5 x 2.7 meters) offers accommodation (with kitchen, bathroom, bed, and seats) and can be connected to other units horizontally or vertically. The structure is a timber frame reinforced by plywood boards on both sides. The cabin can be fixed on the ground either by steel anchors or removable concrete cubes. The interior treatment is changeable and flexible. Unit’s furnishings can be used in various site contexts.

The project has been realized on the grounds of the Ljubljana castle. Now it serves as a temporary library where each floor contains books on various topics. The underpasses with a beautiful view of Ljubljana serve for reading and rest, similar to the concept of the library under the canopy – the readers can enjoy the books under the chestnut. The facility, both equipment and construction, and facade promote Slovenian woodworking and traditional skills of wood crafts and carpentry.
