Description

The Gässli5 project explores how circular construction can be implemented within a specific architectural context. The Gässlihaus is among the oldest largely intact historic houses in the Werdenberg region. After being removed from the heritage protection register, relocation became the only means of saving it from demolition. The log structure was carefully dismantled and reconstructed at a new site within the village. It is complemented by a new rammed-earth building – a house made from natural materials that is fully recyclable and can be returned to the natural material cycle at the end of its lifespan. Missing or damaged timber elements were sourced from other demolished buildings in the village, extending the local building tradition through material reuse. The historical structure was preserved in its material and spatial simplicity; technical interventions such as insulation and building services were deliberately omitted. The new building forms an ensemble with the historical house. It is constructed from load-bearing rammed-earth walls, glue-free timber floor structures, and hemp insulation. The spatial organisation combines an open ground floor with a compact apartment above. This arrangement allows for flexible use as a community house, dwelling or workshop. Depending on the configuration, the historical building can be used together with the new structure as a three-season house. The ensemble is embedded within a permaculture garden featuring edible plants, ponds and dry habitats. The project was conceived as a statement against the ongoing culture of demolition and waste in the construction industry, and as an argument for the reuse of existing building stock. At the same time, it serves as an experiment in challenging prevailing standards and rethinking sufficiency in architecture.
