"Casa Acton questions the purpose of architecture and its relationship with the natural world," say the architects at Archier. "While the building is lightweight to ensure it can be easily moved, it does not feel insubstantial, due to sandstone flooring, painstakingly laid over many months, that provide a tactile surface underfoot, significant thermal mass, and a primal sense of permanence. Though the cabin is modest, it feels spacious thanks to a 24-foot-wide, floor-to-ceiling window. Strategically oriented due north, it visually extends the sense of space into a landscaped garden and the surrounding bushland."
