Located in Byron Bay, this 100 per cent natural pool is the first of its kind in Australia due to its size and scope, so Atlanta Building is a deserving winner in this category. The 220,000-litre pool consists of freeform concrete walls, a feature concrete-sprayed infinity wall/edge, in-water garden bed with plants to assist filtration, a timber-clad island pool deck, a fire pit and a Japanese hot tub. The natural setting of this pool harmonises into the backdrop of the surrounding forest. With the added features of the Japanese-style hot tub and pool island deck, the swimming pool is truly unique and special.
