A new chapter
The replacement of the Neue Steinermühle, a historic mill in the village of Alberswil, with a new building offers an opportunity to continue the history of Switzerland's first industrial mill in a modern, yet respectful manner. The exterior of the Mülihof reproduces the massing and composition of the existing building while creating a new interpretation - a 'cast' - of the original in simple garb that is tailored to its new uses.
The Neue Steinermühle forms the core of a historic ensemble of buildings and is a landmark in the natural and cultural landscape of Kasteln. Refurbishment turned out not to be an economically feasible option, so an alternative solution with long-term viability was developed in close cooperation with the building conservation authorities.
The historic turbine hall is being restored and a new hydroelectric power plant installed there, which will meet 100 of the energy needs from a renewable source. So that the Mülihof can be used as a hotel and residential building, it is being given a new primary structure that also gua- rantees future adaptability. The use of the Mülibach for producing electricity and the economically and ecolo- gically optimized building services are in keeping with the architectural concept and contribute to the creation of a sustainable new building in the mill ensemble.
