Project description
The Zeughaus building built in 1919 by Alfred Ramseyer and Fritz Hiller and the elongated storage building built in 1985 were fully renovated for their new owners, the cantonal police and other administrative departments of the Canton of Appenzell Ausserrhoden. The timber construction of the storage rooms was statically reinforced. The head building of the five-storey building was completely gutted and fitted with new reinforced concrete walls and ceilings. The new threestorey annex (top floor in timber construction) was built on the existing cultural heritage area.

Project description
The Viehmarkthalle, also known as Chälblihalle, has stood in its place since 1869 and is used by the residents of Herisau for various occasions. After securing the structure in 2005, the complete restoration of the building began in 2010, allowing residents to continue using the building and preserving its charm for the next generation.

CHF 4,200,000

Project description
After a very short construction period, the finished building was
inaugurated on 29 May 2010. The dominant, angular, wooden building houses the fire brigade as well as the Wallisellen utility works with its offices, workshops and storage rooms. Thanks to the optimal room layout, both occupants are able to use the synergies, theory room, lounge and terrace without getting in each other’s way. The building meets the goals of the „2000-watt society“, as is evident from the thickly insulated walls, the visible building
services, the mixture of wooden and concrete materials and the photovoltaic system on the roof. The deadlines and construction costs were met.
