Renovations, heritage and volumes

For homeowners planning renovations in Wil, official register figures show that 467 out of 523 known buildings are under heritage protection. Engaging with the municipality early is essential to navigate permit requirements. Data coverage is partial as no information is available regarding the renovation year. Furthermore, the volume data for 2083 houses reflects standards other than SIA 416, and no median volume is recorded. Consequently, when calculating the scale of heating or insulation works, you should rely on professional site assessments rather than these register figures to ensure accurate planning for your specific property project.
