Renovations, heritage and volumes
For homeowners planning renovations in Confignon, please be aware that current data coverage from the official building register is partial. With 802 total buildings recorded, key metrics such as the renovation year, heritage protection status, and building volumes based on the SIA 416 standard are currently unavailable or not measured. Because these official figures are missing, we strongly advise you to contact the municipality directly before starting any major energy efficiency or structural work. Consulting local authorities early will help you clarify specific property requirements and ensure your renovation project proceeds smoothly despite the current data limitations.
