The structure was built without the use of power tools from locally sawn Red Pine. Construction was completed in nine days under the guidance of architect Sami Rintala (Rintala Eggertsson) and Arboreal. The shelter was built spontaneously and collectively without the use of drawings, simply by arranging and adjusting elements until the group agreed on the correct design. From footings to floor, to columns, walls and roof: each part was built in response to the former but without predetermining what was to follow. The result was an intimately site-specific structure that responded to the adjacent avenue of birch trees, the gently sloping ground and the serpentine edge of the nearby lake.
