About Ondsauna Sauna
Ondsauna je sauna smeštena unutar šume. Vertikalni spoljašnji zidovi grupisani su oko prostorije za saunu, odražavajući uzlazni rast drveća. Spiralna staza vodi do prostora za odmor na krovu. Ulaz se nalazi 250 milimetara iznad nivoa tla, terasa za hladno kupanje na 1000 milimetara, a krov na 3250 milimetara, tako da je kretanje od saune preko hladnog kupanja do otvorenog prostora vertikalno. Nepravilan poligonalni plan i klupe pod tupim uglom usmeravaju vizuru i omogućavaju posetiocima da sami biraju nivo interakcije.

- Unique Properties
- Trees grow endlessly upward, a concept reflected in the vertical exterior walls clustered around the sauna room. A spiraling path leads upward to a rooftop relaxation space, mirroring the building's form. The sauna entrance is at GL+250, the cold plunge deck at GL+1000, and the rooftop at GL+3250, so the transition from sauna to cold plunge to open air follows a vertical flow. Viewing the forest at treetop height allows one to share in its growth rhythm.
- Dimensions & Packaging
- The irregular plan was chosen to allow the passage and expansion of the line of sight and to adjust the degree of intimacy, which was rationally solved by the 150mm CLT floor slab. The elimination of beams has eliminated non-perpendicular joints in the structure, contributing to labor savings in site work. The rational walls of the scale module are discretely assembled and the CLT slab connects them. This structural form itself can be described as a sociopetal structure.
- Production Technology
- An irregular polygonal floor plan guides sightlines, creating varied scenic views. Research shows conversations are twice as frequent at 90 degrees versus side-by-side. Here, strangers sit together, so we chose obtuse-angled benches to balance interaction and privacy, encouraging conversation without intrusion. Varied seating allows for different levels of interaction, while the overall arrangement around a fire fosters a shared experience.
- Inspiration
- In a sauna, strangers sit nearly naked in close proximity, creating potential intimacy. Yet in Japan, public saunas haven’t fostered this sense of community. By aligning with Japan’s unique sense of closeness, we aim to create a sociopetal space, encouraging shared understanding without forced intimacy. “Non-intrusive” walls balance connection and separation; their verticality resonates with the forest, while their spacing draws nature in and modulates closeness among neighbors.
