Saun

Most saunas in Australia are built using imported European or American timbers. Their construction is often complex, relying on multiple layers of materials, including plastics and other unnatural or lower-quality components. When exposed to extreme heat, these materials can release harmful chemicals.This layered construction not only increases costs, but also adds to the product’s environmental impact. The result is often a compromised sauna: one that is less healthy for users, less sustainable for the environment, and lower in overall quality.

Saun uses locally sourced, end-of-life Macrocarpa trees, commonly known as Monterey Cypress. A close relative of cedar within the Cupressaceae family, these trees were introduced to Australia and widely planted as windbreaks on rural properties. Today, many are reaching the end of their life due to age and the spread of Seiridium cardinale, a fungal disease affecting cypress species.Saun is built using simple, traditional log construction techniques. Solid timber logs are notched to interlock, requiring no additional wall layers. The timber itself forms the structure, as well as the interior and exterior surfaces.

Saun’s introduction of locally sourced Macrocarpa timber creates meaningful commercial, environmental and societal impact. Commercially, it brings material innovation to the sauna industry, supports local milling, strengthens regional supply chains, and helps balance a market dominated by imported products. Environmentally, using sustainably sourced timber reduces reliance on overseas materials and encourages lower-impact fabrication practices. Societally, the project gives users greater choice while promoting a stronger connection to local materials, craft and place. By proving Macrocarpa’s suitability for sauna environments, Saun also pressures competitors to improve the sustainable value of their products, raising expectations across the industry and benefiting local communities.

Saun’s stand-out design lies in the balance between primal simplicity and refined contemporary craft. Its traditional log construction forms a singular timber shell: solid, elemental and deeply tactile. This robust enclosure is elevated by precise architectural detailing that supports the sauna ritual while maintaining a quiet, sculptural presence in the landscape.The building is grounded on locally sourced natural boulders, allowing the timber form to feel anchored to its site rather than placed upon it. Carefully positioned openings protect privacy and encourage stillness, reflection and self-care, offering a more intimate alternative to the large glass doors and expansive windows commonly seen in sauna design.The ritual begins at the entry with a “handshake”: a custom-made handle by a local blacksmith, crafted from solid flamed metal with a textured finish. This tactile element becomes a sensory anchor, marking the transition into the sauna experience. The floor-to-ceiling pivot door integrates seamlessly into the log shell, reinforcing the purity of the form.Inside, three bench levels provide flexibility for up to four users, including the option to lie fully on the upper level and enjoy the steam. Above, a sharp metal blade roof appears to rest lightly on the solid timber body.
