Renovations, heritage and volumes
For your renovation projects in Grenchen, the official RegBL figures provide essential insights despite partial data coverage. With 4 buildings listed under heritage protection, it is crucial to contact the municipality early to navigate permit requirements. The median building volume of 755 m3, derived from a limited set of 4 measurements, helps define the scale for your insulation or heating upgrade plans. Since renovation years are not recorded and volumetric data is sparse, conducting an on-site assessment remains a necessary step to ensure your renovation budget and planning are accurate and reflective of your specific property.
