Renovations, heritage and volumes

For your renovation plans in Therwil, the official RegBL figures provide essential guidance. With 715 buildings under heritage protection, it is vital to contact the municipality early to discuss permit requirements. Regarding building volume, the median is 782.5 m3. However, please note that this figure is based on only 16 properties measured according to the SIA 416 standard, while 1894 properties use other standards or are categorized as unknown. Consequently, data coverage for volume is partial. Furthermore, no specific data regarding the renovation year is recorded, which should be considered during your project assessment.
