Description

The early 19th-century industrial building is a strong testament to early industrialisation and the use of the River Worble’s water power. A mill race along the base once drove production and shaped the spatial structure. Over time, the building was repeatedly extended and adapted; the current transformation continues this process, translating it into a contemporary residence. The architectural approach is based on a careful continuation of the existing fabric. Historical traces such as wear marks in the masonry, ceiling openings and circulation corridors remain visible and define the identity. New elements are clearly legible as contemporary interventions, creating deliberate contrasts. The tripartite division into south, central and north sections is retained and structures the new programme. The former threshing floor becomes the central access and communal space, linking the apartments and the roof level. An internal courtyard brings daylight deep into the building and establishes visual connections. Interventions were limited to what is necessary. Unexpected structural weaknesses required targeted reinforcement, particularly in the balconies. These measures meet current standards while harmonising with the historical appearance of the building.
