Balliswil Castle Renovation by LVPH Architectes: A Sensitive Dialogue Between Heritage and Modern Living
Balliswil Castle is transformed into three reversible apartments using fir wood and brass, preserving historical integrity with minimal intervention.
Architects: LVPH Architectes
Nestled in the rolling green fields just 6 kilometers from Fribourg Cathedral, the hamlet of Balliswil in Düdingen, Switzerland, is home to the historic Château de Balliswil—a manor house surrounded by traditional agricultural buildings. In this serene and bucolic setting, LVPH Architectes has undertaken a remarkable adaptive reuse project that breathes new life into the castle while preserving its historical integrity.

A Reversible Transformation: From Château to Contemporary Living
The primary concept of the project centers on a reversible transformation. Rather than altering the character of the château permanently, LVPH Architectes proposed a subtle division of the existing structure into three individual apartments, aligning with the château’s original entrances. This intervention is both respectful and sustainable—reversibility ensures the architectural unity and cultural continuity of the heritage site over time.
Importantly, the renovation was approached collectively rather than piecemeal. This holistic mindset allowed the architects to maintain the building’s spatial coherence, preserving its historical atmosphere while discreetly introducing modern residential functions.


Material Strategy: Fir Wood and Brass with a Patina of Time
Informed by the principle of minimal intervention, the design team opted to act only on elements that were missing, deteriorated, or beyond repair. Rather than covering or replicating historical details, they inserted new material layers that contrast subtly with the old.
Two materials dominate the palette: solid fir wood and brass. These materials were carefully selected for their natural aging properties—both evolve visibly over time, developing a patina that contributes to the evolving narrative of the space. Fir, in the form of 4cm x 4cm stained and assembled battens, is used throughout the interiors to form flooring, partitions, ceilings, built-in furniture, and cabinetry.
This economical and tactile approach using tile battens results in finely crafted surfaces with bespoke paneling patterns. These new insertions never overshadow the old—they highlight what’s missing and celebrate what remains.


Custom Furniture as Architectural Continuity
Furniture within Balliswil Castle is not merely functional but architecturally integrated. Custom-built for each room, these pieces respond to heritage preservation constraints—allowing installations to remain freestanding and avoid impacting historic walls or frescoes. The resulting elements serve dual or even triple purposes: benches, chaise lounges, headboards, screens, and storage, all designed to echo the spatial rhythm of the original architecture.
Brass, on the other hand, is introduced sparingly, mainly in wet areas like bathrooms and kitchens. Its application varies—waxed finishes are used for fixtures, while raw brass is left untreated for items like sinks, trays, soap holders, and light-reflecting wall panels. Over time, the oxidation of brass deepens the project's narrative, creating a living material memory of everyday life within a historic space.


Honoring History Through Subtle Innovation
Rather than imposing a bold architectural statement, LVPH Architectes’ intervention is intentionally quiet, allowing the château’s layered history to take center stage. The project champions craftsmanship, modesty, and long-term sustainability through minimal, reversible design strategies.
