Slovak Forest Sauna Lifts Off the Slope Instead of Digging It

A 269-square-foot sauna completed in 2025 at the Zaježová Educational Centre in Pliešovce, central Slovakia, avoids major excavation by resting its timber support structure on concrete footings above the sloping ground. Guča arch., the Bratislava-area practice behind the project, framed the brief in practical terms: the original sauna at the educational center, in the architects' words, was not comfortable enough.

The response gives changing, cooling down, and resting their own distinct places within a small footprint. That allocation, not the exterior image, drives the design.

What does the structure actually do?

The ground continues underneath the building. The architecture takes responsibility for making the levels work rather than rearranging the hillside into a building pad. Timber frames sit on concrete footings, lifting the whole volume above the slope.

The exterior borrows its logic from an everyday Slovak sight: stacks of timber left to dry in the countryside. Those arrangements use gaps between boards and a lightweight metal covering to let air through while keeping rain off. Guča arch. transfers that visual logic to the sauna's facade and roof — a reference drawn from the place itself, not from a luxury resort brochure.

The construction carries the character:

• Repeated larch frames stay exposed outside, giving the facade depth and a readable rhythm.
• Panels fit between the frames.
• Large spruce boards finish the interior and also help brace the structure.

The firm followed a direct design-build process, keeping the design closely connected to its execution. The building reads without requiring an elaborate explanation of what its surfaces symbolize.

How does the plan divide the space?

Three principal spaces organize the interior. A wooden platform brings visitors into a central vestibule that serves as both changing area and junction. The compact sauna room occupies the lower section. The larger resting space sits uphill, opening toward the trees through substantial glazing.

The difference in proportions is deliberate: enclosure for the heated room, more space and a longer view for the time spent recovering. In a building this small, giving the resting area a generous share of the plan is a meaningful decision. It suggests that sitting still afterward deserves more than a spare bench beside the entrance.

Across from the entrance, an outdoor terrace holds a cooling tub and looks toward the forest. The elongated footprint also separates the center's more public grounds from this quieter side, using the building itself to establish privacy. The changing area links the heated room, resting space, and terrace into one sequence rather than three unrelated amenities.

Is it a transferable template?

Not directly. The form grows from this particular slope, the neighboring orchard and forest, and an educational center focused on ecology and personal development. The transferable idea is more modest, and more useful for practitioners: decide how people will move through a place before getting distracted by how impressive the exterior might look.

There is a practical footnote. The architects' project description earmarks the original sauna for reuse as firewood storage — a building inspired by drying timber gains an actual wood store nearby, without demolishing the old structure. The project's appeal lies in decisions of that scale: enough room to rest, a sheltered outdoor edge, and a hillside left undisturbed.
