Origma Hut is a single room, off-grid forest retreat custom-designed and built by Gary Warner and Philip Sticklen. All materials for the building were brought to the bush site on the back of a ute, down a rough 7km track.The building comprises a galvanised steel frame clad with1200x2400x25mm form-ply sheets, sitting on sandstone piers. The piers are recycled from discarded 1880's fence footings of a Sydney public park.The inverted roof profile delivers rainwater to a large box gutter feeding a 5,000 litre tank. The roof is made of solarspan, a steel faced insulation filled panel system. Intricate galvanised flashing detail was cut and shaped by hand.Brass detailing completes the materials palette.The interior space is lined with recycled wool blankets covered with 18mm plywood sheeting. Powerful industrial magnets are used for temporary attachment of textiles and support hooks to the steel frame.A composting toilet, designed and built to complement the main building, is sited at a distance from the hut.
