Hi guys from what I understand this method of construction was used in Pompeii also due to earthquakes, they used it as the walls could breathe making the house thermally sound, they even installed lead piping for hot water in the walls for heating, apparently they placed vertical poles in the ground through the gabion walls to the top to keep the walls vertical and to attach the top plates so to pitch the roof, there is a family here in Victoria who has built a Gabion house and the council engineers made him put steel vertical columns in the gabion walls to keep the building vertical and also for pitching of the roof, I’m looking at building the same way and using hemp cement rendering inside and outer walls with hot water piping for heating, and reinforced hebal cement ceilings for thermal insulation, anyway hope this adds some light on your project, good luck with it, kind regards Peter
