Conversion of Appenzeller building with concealed construction method

Waldstatt, Switzerland

Layered wood construction

The traditional Appenzell log house was upgraded energetically and adapted to modern living standards. The 120-year-old log walls, previously hidden behind faded façade panels, were uncovered and made visible again.

The roof was stripped to the timber structure, reinforced, and fitted with a new tongue-and-groove lining and insulated roof build-up. An integrated photovoltaic system was later installed.

Damaged floors were replaced with new hollow-box ceiling elements. Due to their height, the basement and upper floor ceilings were repositioned to achieve a minimum room height of 1.96 m. Several new load-bearing walls were added. The staircase required an offset layout due to limited headroom.

The façade received sky-blue fibre-cement cladding and new aluminium-wood windows. Traditional detailing such as blind frames and mullions was preserved. Apprentices gained valuable experience, highlighted by the independently built entrance windbreak.
