Between Today and Yesterday
Sensitive Restoration of a Historic Mill Complex
Nestled in rural countryside stands a mill complex from the late 16th century. Over the centuries, this four-sided compound has undergone repeated transformations, expansions, and fires. Recently, a Frankfurt-based family acquired the property to create a shared home for themselves and extended family. But before the estate could become a rural sanctuary, it needed careful, architecturally sensitive restoration. Weinzierl was tasked with transforming the project into a place where history lives on, while delivering modern comfort without unnecessary complexity.
The first two construction phases encompassed converting the former cattle barn and renovating the northern carriage house. Prior renovations from the 1980s had left the buildings with fragmented floor plans and incomplete finishes. The most demanding challenge: the structural and hygrothermal performance of the natural stone walls made of slate-like layered rock, which cannot withstand drying out. The solution came through a mineral, moisture-regulating facing—a structural intervention that preserves integrity without altering character. Simultaneously, the eastern terrain was restored to its original elevation, restoring direct access to the breakfast terrace. This required completely replacing the drainage system and connecting it to the on-site root treatment plant. Energy-wise, the complex was modernized throughout: three outdated heating systems were replaced by a central pellet heating unit with thermal storage, paired with solar and PV installations. Power comes from a small water turbine fed by the mill's own pond.
The design philosophy was simple: strip back to original substance, recover what was there, and renew with authentic, honest materials. The project employed reclaimed timber beams, hand-split larch shingles, mineral plasters, and breathable finishes. Interior design—particularly the kitchen—evolved through close collaboration with future residents: custom-made carpentry in aged oak, entirely free of particleboard or synthetics. Honoring the owners' vision, the property steps confidently into the future while honoring its past.
