For your renovation projects in Ittigen, the RegBL figures provide vital context regarding your property. Currently, data coverage for house volume and renovation years is only partial, which limits automated estimation capabilities. Although official records indicate no heritage-protected buildings, we strongly advise contacting the municipality early to confirm permit requirements. Since the volume for the 840 recorded houses does not follow the SIA 416 standard, you will need to provide precise measurements when planning your thermal insulation or heating upgrades. Accurate site-specific data remains essential for determining the scope and budget of your renovation.
