A house built out of concrete-impregnated burlap.
"Sited on the ridge of a hill in Eltham in Melbourne’s north-east, the house is conceived as a tent-like encampment consisting of two structures – a main house and a secondary structure that was originally a garage and studio. It was constructed using a method known as the ctesiphon system, which formed a series of catenary arches.
“Borland had read in the English magazine Architectural Review of a British engineer’s adaptation of an Italian method of forming thin shelled concrete vaults by spraying cement over chicken wire reinforcing suspended on formwork,” Hamann wrote.
The ctesiphon system involved applying layers of cement laced with a waterproofing agent to hessian-covered catenary timber arches.
