Australian firm Luigi Rosselli Architects have completed what they are calling the country's longest rammed earth wall, as part of a residence for seasonal workers on a cattle ranch. Gravel from the nearby river and water from the local well was used as a binder in these walls, and rammed by hand, creating a gorgeous, layered look characteristic to rammed earth walls. The floor is poured concrete slab, given the same colour by utilizing the same gravel and aggregates from the river.
