Renovations, heritage and volumes

For your renovation plans in Basel, the RegBL data provides essential guidance. With 2299 buildings under heritage protection, it is vital to contact the municipality early to discuss permits. While building volume figures according to the SIA 416 standard are unavailable, the data coverage for renovation history is complete. The median renovation year is recorded as 2024, reflecting recent activity in the area. Please note that for certain technical aspects, data coverage remains partial. Consequently, you should conduct a thorough on-site assessment to accurately plan the scale of your insulation or heating works, as official figures do not cover all metrics.
