Renovations, heritage and volumes

When planning renovations in Diepoldsau, consulting the federal building registry data is a vital first step. Among 1635 recorded buildings, 15 are currently designated under heritage protection, necessitating early coordination with municipal authorities to secure required permits. Please note that data coverage remains partial; no information regarding renovation years is available, and building volumes according to SIA 416 standards were not measured for the 1315 residential units listed. Without these specific metrics on building scale, homeowners should prioritize professional on-site assessments to accurately evaluate the requirements for insulation or heating system upgrades within the municipality.
