About Ondsauna Sauna

Ondsauna je saunová budova umiestnená v lese. Vertikálne exteriérové steny sú zoskupené okolo saunovej miestnosti a odrážajú vzostupný rast stromov. Spirálovitá cesta vedie k relaxačnému priestoru na streche. Vstup sa nachádza 250 milimetrov nad úrovňou terénu, terasa pre studené kúpanie vo výške 1000 milimetrov a strecha vo výške 3250 milimetrov, takže pohyb od sauny cez studené kúpanie až po otvorený vzduch je vertikálny. Nepravidelný polygonálny pôdorys a lavice s tupými uhlami usmerňujú pohľady a umožňujú návštevníkom zvoliť si vlastnú mieru interakcie.

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.
