Six Frames House by Lukas Lenherr Architektur: Merging Heritage and Modern Living in Männedorf, Switzerland

Located in Männedorf, Switzerland, the Six Frames House byLukas Lenherr Architektur is a striking example of adaptive reuse, transforming an 1850s barn into a contemporary residence while preserving its historical essence. Covering 149 m², the project reinterprets traditional Swiss rural architecture through modern interventions that emphasize openness, structural honesty, and ecological sensitivity.

Preserving History Through Innovative Structure

The design introduces a slender wooden framework of six spruce frames, carefully integrated within the existing barn structure. These frames initially support the historic building during construction but remain visible afterward, defining interior spatial sequences. Vertical and horizontal panels stabilize the structure and generate distinct rooms and transitions, while various openings establish visual and spatial connectivity.

Spanning three floors, the interiors unfold like a continuous, vertical living space. The arrangement draws inspiration from the American Shotgun House, allowing rooms to maintain semi-open relationships. Interior windows, flaps, and strategically placed catamaran nets create dynamic visual connections and flexible retreats, fostering a sense of openness while maintaining privacy.

Open Living and Functional Design

A central open staircase connects all levels, including a basement workshop illuminated by skylights, linking the subterranean workspace to the main living areas above. This design emphasizes transparency and continuity, enabling the wooden house’s structure to be visible throughout. The interplay of light, beams, and minimalist furnishings enhances the sense of warmth and tactile engagement within the home.

Exterior Transformation: Tradition Meets Modernity

Externally, the barn retains its original volume and roofline, maintaining the heritage character within the protected ensemble of backyard houses. A new clapboard facade of silver fir wood was treated with the Japanese Yakisugi charring technique, ensuring durability for generations. Windows on two sides of the façade are discreetly shaded by manually adjustable black wooden slats, controlling light and privacy while subtly signaling the home’s contemporary function.

Sustainable and Ecological Approach

Sustainability is central to the Six Frames House. The project carefully records historical construction methods and integrates ecological strategies, from material choices to energy-conscious heating systems and long-lasting wood treatments. The collaboration with manufacturers such as Focus, Gessi, Occhio, BORA, and Group-Corbat SA ensures functional, aesthetic, and environmentally responsible solutions throughout.

Six Frames House demonstrates how adaptive reuse can harmonize heritage conservation with contemporary architectural innovation. Its open spatial planning, visible wooden framework, and ecological strategies exemplify thoughtful design that respects history while enhancing modern living experiences.
