Slovenian architecture firm OFIS Architects developed a living unit. Research for the cabin was initiated by OFIS Architects and Permiz, C+C, C28 and AKT to develop a self-contained wooden shell, flexible and adaptable for different locations, climate conditions and terrains. This compact house can be used as holiday cabin, a hideaway, treehouse or even a temporary habitation for research. OFIS Architects’ basic living unit (4.50 m x 2.50 m x 2.70 m) offers accommodation, including a kitchen, bathroom, bed and seats. It joins horizontally and/or vertically and can be upgraded to twins-sized, triplets or similar. The structure is made using timber frames, which are 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 and the unit furnishings can be used in various site contexts.
