The Nautilus: A Vessel of Universal Design
With a pencil and one of his well-worn project books, he began sketching 2D shapes — experimenting with spirals, curves, and chambers in search of something that felt both functional and inherently balanced. The goal wasn’t just engineering — it was harmony.
One form stood out: a soft, unfurling spiral reminiscent of the koru — the curled frond of the punga fern he’d often stopped to admire on runs through the Wentworth Bush of Whangamatā. The sketch was refined, repeated, and finally evolved into a 3D CAD model, bringing the organic concept into technical reality.
From those roots, the Nautilus Hot Tub was born.
More than a sculptural marvel — The Sulis Nautilus Hot Tub is a physical embodiment of one of the most profound patterns found in nature: the golden ratio
This ratio appears in the spiral of galaxies, the twist in animal horns and the structure of DNA. It’s how the body balances, and how storms breathe across the sea.
Across cultures, this ratio has been revered as a sign of cosmic order, a sacred geometry that reflects the intelligence of nature — building complexity through simplicity. It's a reminder that everything, from the smallest shell to the largest storm system, follows patterns — and those patterns are beautiful.
Whether nestled into a landscape or standing as an architectural feature, the Nautilus is more than a hot tub. It’s a living expression of the universe’s design code — an invitation to immerse, unwind, and return to source.
