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.
