Administrative Building in Frauenfeld with Distinctive Passage

Urban timber construction for the Thurgau administration

After around three years of construction, the new administration building "Vorstadt", designed by Gäumann Lüdi von der Ropp Architects, was officially inaugurated in December 2025. Blumer Lehmann was responsible for the timber construction planning, the production and assembly of the prefabricated elements, and the timber façade of the building.

The "Vorstadt" administrativ building is the first cantonal building to meet the SNBS 2.0 sustainable building standard. The centre section of the extension is designed as a bracing reinforced concrete structure. The side wings with 21 office areas house around 300 workplaces, as well as a cafeteria and meeting rooms. Timber as a material contributes to achieving the standard’s aims: a significant level of material re-usability, a high level of thermal comfort and optimal indoor air quality. The timber for the supporting structure comes entirely from the Thurgau cantonal forest.
