The project
The cantonal preservation authority demanded that the existing supporting structure be preserved and adapted to the changed usage characteristics. The initial situation: Basically, the barn measures an area of 48m x 16m and a height of 13m. The roof structure in the form of a gable roof was originally stabilized from trusses with wooden beams in two levels. The connections of the individual beams to each other were made in the traditional manner at the time, and pressure connections such as offsets were secured with wooden dowels as far as possible. The trusses, rafters and purlins have a hand-beaten surface common at that time.

The construction method
To ensure the load-bearing capacity of the barn under the existing loads and additionally introduced loads such as the hay crane, new three-hinged trusses were inserted under the existing supporting structure. In the first floor area, walls / ceilings were moved and reinforced to meet the usage requirements of modern animal husbandry. Along the entire length of the barn, a new grapple was installed in the period area to distribute the feed to the desired boxes.
