Liina is made of timber and timber-based materials. A series of prefabricated sandwich panels that can be easily transported and assembled, and can be flat-packed into a small space. Six panels are joined together with simple, repeated timber-dowelled joints to form a frame and tightened using nylon straps (‘liina’ in Finnish), like those used for the transportation of cargo. The strap creates air-tight joints without any metal fasteners or the use of electric-powered tools on-site. The frame is then tilted up and stacked one by one with the other frames. Finally, the building is protected from water and UV damage with a tent-like canopy.

The modularity of the design makes it possible to add or subtract frames.
