Sauna Los Batanes is a compact lakeside structure in Valle de Bravo, Mexico, built from oak recovered from fallen trees on the property. Set on stone supports above the ground, the sauna organizes changing, washing, heating, and cooling around an open deck facing the water.

Timber Continuity and a Low-Impact Ground Strategy
Sauna Los Batanes stands at the edge of a lake on a ranch in Valle de Bravo, where the material logic begins before construction. Its oak structure and cladding were made from trees that fell on the property, establishing a direct relationship between the building and the site’s long material history. Rather than treating timber as an abstract commodity, the project retains the evidence of its local origin through broad beam sections, visible knots, checks, and grain.
The building is lifted on six large river stones placed over compacted-earth footings. Heavy timber beams span between these supports and are stacked to form a raised plinth. This strategy limits disturbance to the lakeshore by avoiding extensive excavation and heavy equipment, while also separating the oak from persistent ground moisture. Rainwater, surface runoff, and low vegetation can pass beneath the floor, keeping the terrain legible below the volume rather than replacing it with a continuous concrete platform.
The beam-to-stone contact is deliberately plain. Hand-hewn oak bears directly on rounded stone without an elaborate visible connector, making gravity and material weight the foundation’s governing expression. The detail also gives the structure a provisional quality appropriate to its setting: it appears placed on the site rather than permanently fused to it. This apparent simplicity depends on careful positioning, load distribution, and protecting the timber from the damp conditions of the lake edge.
Recasting the Sauna Archetype for a Mexican Lakeside Setting
The project reworks the familiar pitched silhouette of the Finnish sauna without reproducing it literally. Seen from the side, the roof becomes a steep single plane that rises toward the lake and projects beyond the enclosed rooms. The resulting wedge shifts attention away from an autonomous cabin form and toward the deck below, where bathing extends into the open air. Its long cantilever creates shelter at the water-facing edge while preserving an unobstructed relationship between the platform and the landscape.
A longitudinal slot divides the roof into two shallow planes and introduces daylight into the otherwise dark timber composition. The opening exposes rafters and separates the roof masses above the central bay, making the building’s construction visible where its enclosed and exterior spaces meet. Rather than relying on large areas of glazing, light arrives from above and through carefully controlled apertures, allowing the sauna to maintain the dimness associated with thermal enclosure.
The roof serves as both climatic cover and social infrastructure. It protects the outdoor shower and resting area from rain while leaving the sides open to shifting air, vegetation, and views across the lawn. At its lower edge, the soffit compresses the view toward the landscape; at the central opening, the sky becomes part of the bathing sequence. The roof therefore mediates between intense interior heat, the cool lake environment, and the deck’s slower occupation.
A Sequence Between Preparation, Heat, Water, and Gathering
Within a footprint of approximately seven by four meters, the plan is organized as a linear ritual rather than a single insulated room. An enclosed changing room occupies one side, offering a private place for preparation and storage. At the center, an outdoor shower opens directly to the deck. The sauna chamber occupies the opposite side and features an L-shaped bench arrangement for up to six people, with the heater positioned as the room’s thermal focus.
This arrangement makes the deck more than a circulation strip. It is the shared territory through which occupants move between dressing, showering, heating, cooling, and resting. The lake remains a constant visual presence in this sequence, even when it is not entered directly. By extending the ritual outside the sauna chamber, the project recognizes that sauna bathing is structured by alternation: heat is followed by exposure to water, air, weather, and conversation.
The open central bay is the key spatial hinge. It separates the two darker enclosed volumes while connecting them through a common platform and roof canopy. From the front, the composition reads as two timber boxes framing a void, rather than as a single sealed object. That void gives the compact building a degree of porosity and lets the central zone function as both threshold and room, accommodating informal occupation that exceeds the sauna’s capacity.
Charred Oak, Framed Openings, and Landscape Perception
The exterior oak is treated with yakisugi, a charring process that darkens the timber surface and improves its resistance to weathering. Here, the treatment does not produce a uniform black shell. The grain, knots, board joints, and fixing points remain visible, giving the cladding a textured, dark brown appearance that changes with moisture and light. The charred surface registers the material’s irregularity rather than concealing it behind a smooth protective finish.
This dark skin is offset by the untreated underside of the roof, where the oak retains a warmer, honey-coloured tone. In wet conditions, the deck and cladding deepen in colour and recede into the surrounding canopy; in low afternoon light, the exposed soffits make the roof plane more perceptible. Across the lake, the compact volume is reflected in the water as a dark counterpart to the cypresses and broadleaf vegetation around it. The palette is restrained, but it is not neutral: blackened oak intensifies the contrast between constructed surface and saturated greenery.
Openings are limited and precisely positioned. A square window in the changing room frames existing adobe and tiled-roof structures on the ranch, while narrow vertical windows at the sauna chamber filter views of cypresses, understory vegetation, and the lakeshore. These apertures do not dissolve the enclosure into glass. Instead, they operate as measured visual instruments, allowing the landscape to enter the dark interior in fragments. The project consequently turns looking outward into part of the sauna experience, alongside heat, humidity, water, and the tactile presence of timber.
